Meeting Results: A Summary of Issues, Questions and Gaps
On November 30 and December 1, 2011, the National Institute of Justice (NIJ) convened a group of experts to form the Firearms
and Violence Research Working Group. After considering the reviews presented and discussed at the meeting and presented below,
the working group identified seven topical areas and subareas that if addressed would advance our understanding of firearms
violence and identify effective strategies that could reduce gun-related violent crime.
Maintain a focus on firearms and violence. In the 2010 review and assessment of NIJ, research on firearms and violence was identified as one of the few topics that
had received sustained, directed and cumulative support. The result, according to that report, was significant advances in our understanding of the aspect of crime in United States
that accounts for the seriousness (i.e., lethality and degree of injury) of violent crime in our society. The Group noted
that NIJ had not in recent years maintained this focus on firearms and violent crime, that no other federal research agency
had addressed this topic, that few foundations supported basic research on this topic, and that the absence of support had
resulted in a significant reduction in the amount of research and the numbers of researchers focusing on this topic. The absence
of long-term support and concentrations of research excellence has resulted in a decline in the creation of new knowledge — basic
The Group concluded that the continuing lethality and seriousness of crime in the United States require continued investment
in gun-related crime issues that should include a long-term commitment to topics and centers of excellence and require an
ongoing mechanism for research agencies to expand and coordinate their efforts. The maintenance of a technical working group
on this topic would assist NIJ in providing leadership in this research area.
Advancing basic knowledge on the acquisition of firearms used in crimes and defensive gun use. Largely due to the work supported by NIJ, we have accumulated a comprehensive description of the role of firearms in crime.
Unfortunately, these "facts" are dispersed across many disciplines, are not widely known, and are sometimes distorted for
partisan reasons. Although the National Research Council (NRC) report  documented many of these "facts" the Group recommends that the research working group on firearms and violence be tasked
with assembling a document that summarizes these findings and providing a review of the document that would assure widespread
acceptance and recognition of what we currently know about the relationship between firearms and violent crime.
In the 1990s NIJ supported research to determine how individuals acquired the firearms that were used in the commission of
crimes. These studies, although important additions to our understanding about the acquisition of firearms by criminals, are
now almost 20 years old, and the methods used in these studies need significant improvement. The Group suggests that new efforts
be undertaken to use improved methodologies to study and better understand the ways in which all criminals who use guns in
the commission of their crimes acquire those guns. The first step in this effort would be the development of methodologies
that would provide better estimates of gun acquisition than those used in the 1990 studies.
Studies of defensive gun use to date have focused primarily on estimating the number of times guns are used to prevent crimes.
The NRC report identified the limitations of these approaches and established what appears to be today a reasonable estimate
of the range of the number of times guns are used to prevent crimes. The next step in this research area should focus on the
process of defensive gun use. This would be an effort to move beyond an estimation of extent to an understanding of the decision
process that occurs during a potential crime in which a potential victim uses a gun to deter the criminal. The same kinds
of studies should be undertaken in the topical area of right-to-carry. While the debate continues on the impact of right-to-carry
laws on crime, almost no information is available on when and where individuals who have been granted the right to carry a
weapon actually use the weapon to deter crime. Nor have there been detailed cost/benefit analyses of the actual use of guns
for defensive purposes. Getting into the "black box" of defensive gun use will allow us to move beyond debates about the extent
of defensive gun use to an understanding of when and how it happens. This has become even more important with the expansion
of "stand your ground laws" which are intended to further establish the legal foundation for defensive gun use.
In recent years, police have developed numerous violence reduction programs that target gun violence. NRC has determined that
these programs are highly effective in achieving gun violence reductions. In some instances, the communities that are the target of these violence reduction efforts have resisted or not been properly
prepared to cooperate with the police. Although we understand that the community needs to play an important role in violence
reduction, little research has been conducted to identify the sources of community resistance. The Group believes that a focus
on understanding these sources of resistance and how to develop violence-reduction programs that are supported by the community
is critical. Related to these issues is the question of why concentrations of gun violence persist and return after successful
interventions. Understanding how to reduce gun violence for the long term will be an important part of the effort to improve
our knowledge of how to effectively mobilize the community in gun crime reductions.
Criminal justice topical areas. Hot spots policing is established as an effective evidence-based intervention for gun violence. What is not known is why
and how these interventions work. Is it increases in guardianship; deterrence; social space uses — why do the variety of interventions
labeled hot spots work, why do they vary in their effectiveness, and why do some persist longer than others? If we could answer
these questions, we could further develop this already effective intervention.
Many critics of new efforts to reduce gun violence suggest that what we need to do is more fully enforce the prohibitions
in place, especially for high risk offenders. Included in this suggestion is the issue of the optimum length of some prohibitions.
The Group agreed that there has been no research to date to address the issue of full enforcement of existing federal and
state prohibitions and little recent work on the issue of their length. This effort would best be done experimentally in jurisdictions
that have available to them a wide range of options including enhanced sentences, restrictions on gun possession for high
risk categories, and alternatives to traditional processing of gun offenders.
As with other aspects of criminal justice processing, little is known about the role prosecutors play in the efforts to reduce
gun violence, especially with regard to prosecutions to disrupt drug markets. In addition, more research is needed on how
bail amounts are set for gun offenses, the impact of the various forms of gun courts, and the impact of differences in how
judges hand down sentences for similar gun offenses/offenders. The group suggests that a concentrated research effort on how
gun crimes and gun market crimes are developed and prosecuted would materially increase our understanding of how to improve
the use of the criminal justice system to deter gun crimes and disrupt gun markets.
Prevention topical areas. The group concluded that prevention continues to be an underdeveloped research area. As the NRC report concluded, no prevention
programs have been rigorously demonstrated to be effective. In part, this is because so little research support has been provided
to this type of research. The group urges the development and testing of gun violence prevention programs based on general
prevention theory. A particular focus should be on collaboration with health systems and providers in terms of the use and
study of individual and environmental level data and interventions, to better target high risk persons and places.
Gun markets topical areas. There was widespread consensus in the group that research on how guns are acquired for criminal use and how those acquisition
lines can be disrupted is vital. This has been mentioned above. In addition to the topics discussed above, this research area
should include studies of the "life cycle" of crime guns (tracing guns from the gun crime to the manufacturer, identifying
all intermediate owners and possessors and their means of acquisition). This research would assist in identifying possible
new ways to disrupt acquisition of guns for use in crimes.
Improving data on guns in the United States. The conclusions of the NRC report on this topic are still true. Improved data on gun possession, gun acquisition, and gun
use are needed. While there are legitimate concerns about the accuracy of current measures and while there are legitimate
concerns about the ability of survey methods to measure such a sensitive topic, the group believes a program of research on
ways to improve measures of these topics is necessary to provide us with measures that have greater acceptability and known
estimates of measurement error. This work could lay the foundation for addressing many of the questions surrounding guns and
violent crime that to date have proven to be difficult to resolve.
Comparative research topics. The group noted that there are efforts ongoing in other countries that touch on all of the topical areas noted above. The
group suggests that it would be useful to monitor these efforts, participate in them where appropriate, and establish multinational
research efforts when necessary.
Day One — November 30, 2011
Welcome and Introductions
Dr. Charles Wellford opened the meeting as facilitator and asked participants to introduce themselves and also provide some
information about their connection to research on firearms and violence (see agenda and list of participants).
Dr. John Laub, Director of NIJ, welcomed everyone to the meeting. He said that NIJ is striving to lead research on crime and
justice including firearms and violence. To do that, NIJ is developing a cutting-edge research agenda and building a cumulative
knowledge base. He said that NIJ is giving increasing attention to how scientific knowledge is diffused. NIJ is using translational
medicine as a model and exploring ways that NIJ can develop a translational criminology.
Dr. Laub told the group that NIJ has formed topical working groups in the Office of Research and Evaluation to assist the
field in the identification of key research questions, issues and gaps in knowledge. He also said that NIJ is promoting research
on issues such as firearms and violence by coordinating and creating partnerships with other organizations, agencies and constituencies.
He suggested that challenges and obstacles make it difficult to work with a topic such as firearms and violence as it is full
of ideology, but with little research or established methodology. In this regard, Dr. Laub expressed appreciation to participants
for volunteering to help NIJ and the field.
The NRC Report — Charles Wellford
Dr. Charles Wellford from the University of Maryland reviewed findings and recommendations from the National Research Council
(NRC) 2005 panel study and resulting report, Firearms and Violence: A Critical Review Exit Notice. He chaired the NRC panel, sharing editing responsibilities with John Pepper and Carol Petrie.
By 2005, research indicated that higher rates of household gun ownership appear to be associated with higher rates of gun
suicides, illegal diversion from legitimate commerce is an important source of guns used to commit crimes and suicides, firearms
are used defensively many times per day, and some types of targeted law enforcement interventions may lower gun-related crimes.
Dr. Wellford reported that the panel found no credible evidence to suggest that right-to-carry laws decrease or increase crime.
Also at the time of the report, there was no research to show that the more than 80 gun violence prevention programs the committee
examined had any effect on children's behavior, knowledge, attitudes or beliefs about firearms.
The NRC panel found that many questions surrounding firearms and violence cannot be addressed with existing data and research.
Existing research and data remain too weak to support policy development. For instance, research concerning defensive gun
use is so disparate in data and methods that huge differences in results cannot be explained. The methodology necessary for
unraveling causal relationships between firearms policy and violence was seldom employed or adequately developed in the research
reviewed by the panel. Many policy dilemmas remained problematic at the time of the report, including the need for public
authorities to carefully consider conflicting constitutional issues, facts and opinions regarding firearms and violence, and
where the balance lies in the costs and benefits of private gun ownership.
Dr. Wellford reviewed report recommendations including federal government support for a systematic program of data collection
and research specifically addressing firearms and violence. Current ownership data are limited and little scientific data
exist on firearms markets. He suggested that the National Violent Death Reporting System (NVDRS) begins to address this problem,
but only 22 states have adopted it to date, and funding support for the states continues to be an issue.
In addition to much-needed development of data and methods, further research is needed on markets, defensive gun use, right-to-carry
laws, suicide and criminal justice interventions. He suggested this meeting of the working group would contribute up-to-date
information to the discussion and identify important research issues, questions and gaps for consideration by the field of
research on firearms and violence.
Criminal Justice Interventions — Ed McGarrell
Dr. Ed McGarrell from Michigan State University presented information on evaluation research involving criminal justice interventions
since the 2005 NRC report on firearms and violence, including gun courts, enhanced sentencing, mandatory sentencing, place-based
and problem-oriented policing, policing gun hot spots, policing violent gun offenders and Project Safe Neighborhoods.
Gun courts. Dr. McGarrell said that specialized courts appear to be emerging as another way to divert gun offenders from the system.
He reported a recent study in Alabama that demonstrated lower recidivism rates among participants, although the research design
was not very strong. Other jurisdictions have begun using gun courts including Brooklyn, N.Y., Cambridge, Mass., Philadelphia,
Pa., Providence, R.I., and Queens, N.Y. He said more research is needed using better methodology.
Enhanced and mandatory sentences for using a gun when committing a crime. The NRC panel reviewed 10 studies involving sentencing for gun crimes, and suggested that there is some evidence of some
impact on some crimes in some locations. Dr. McGarrell said that to date findings are mixed and implementation issues notable
in existing research. It is not unusual for prosecutors, for example, to drop offenses carrying mandatory sentences in plea
bargaining to secure convictions in other charged crimes. Results from one study evaluating Project Exile, which included
gun prosecutions as a main component, suggest that homicide was reduced. However, mandatory sentencing studies have provided
mixed and contradictory results with limited evidence of impact.
Domestic violence prohibitions. Dr. McGarrell summarized three studies that have been conducted since the NRC report assessing reductions in violence as
a result of prohibiting firearms possession by domestic violence offenders. Although results are promising, he suggested more
study is needed in this and other areas of prohibiting firearms from specific groups such as mentally ill persons, noncitizens
and domestic violence offenders.
Place-based problem-oriented policing. More research has been accomplished in the area of place-based and problem-oriented policing since the NRC report. He summarized
a few examples of interventions that have been implemented effectively. Recent evaluations have demonstrated the effectiveness
of Philadelphia's foot patrol and Jacksonville's problem-oriented policing in violent crime hot spots. He suggested that more
research be directed toward the sustainability of intervention effects associated with this type of action research.
Policing gun hotspots. Dr. McGarrell reviewed three recent studies providing further support for reducing gun violence hot spots, but all have some
methodological limitations. Remaining hot spots research issues include the need to demonstrate long-term effects, substitution,
adaptation and deterrence. He reiterated the NRC committee recommendation for sustained and systematic research on the impacts
of different problem-oriented place-based interventions such as gun suppression patrols, targeted policing approaches and
removal of high-risk guns.
Policing violent gun offenders. Dr. McGarrell then talked about interventions with known gun offenders. He highlighted a St. Louis program targeting juvenile
offenders that sent officers to residences to request permission from parents to search the home for guns. They surprisingly
received much cooperation from parents and appeared to have some effect on gun violence. Evaluation research on the popular
Boston Operation Ceasefire program has showed an association between the program and a decline in violence, but the research
design left some efficacy questions unanswered. The NRC committee recommended a sustained and systematic program of research
on focused deterrence and prosecution. A series of other program evaluations have been published in peer-reviewed journals
since then. They found similar results in Indianapolis, Ind., Lowell, Mass., Chicago, Ill., Stockton, Calif., and Cincinnati,
Ohio, with most employing quasi-experimental methods similar to those used in evaluating Boston's Ceasefire.
Project Safe Neighborhoods. As a major Department of Justice initiative launched in 2001, Project Safe Neighborhoods (PSN) funded task forces with all
U.S. Attorneys' Offices in the United States. Dr. McGarrell and Michigan State University provided training for the program
sites and evaluated the overall PSN initiative. Training curriculum for task forces was based on Project Exile (Richmond)
and Boston CeaseFire. He reported that a third to half of the PSN sites used program components such as call-in notification
meetings for known gun crime offenders, probation/parole offender home visits, gun incident reviews, and cooperation with
federal and local law enforcement such as joint gun case screening. The evaluation assessed implementation by looking at the
local level of federal gun prosecution, the quality of local partnerships, and integration of research findings into program
components. Findings suggest that target cities in higher implementation districts saw greater reductions in reported violent
crime. Major limitations involved possible preexisting differences in target treatment and comparison cities. He added that
a recent meta-analysis indicates that focused deterrence strategies may be generally associated with medium-sized crime reduction
Dr. McGarrell briefly reviewed some ongoing research including reentry programs that are targeting violent ex-prisoners with
focused deterrence strategies in Boston and Chicago. Early results suggest that this approach has some impact at the community
level, but the cause of these effects is still unclear. Also, Hawaii Opportunity Probation with Enforcement (HOPE) was evaluated
with a randomized control design, which showed significant reductions in arrests, positive drug tests, probation revocations
and subsequent days in prison. The Comprehensive Anti-Gang Initiative (CAGI), another NIJ-funded evaluation using this approach,
has shown no overall effect. But, it again appears that level of implementation is associated with effects, with high-implementation
sites experiencing greater declines in reported crime than low-implementation and non-CAGI sites.
Criminal Justice Interventions — Discussion
Discussion around criminal justice interventions was far ranging and included place-based, hot spots, and focused deterrence
programs and other strategies targeting firearms violence. Sentencing policy and options and alternative sanctions like specialty
courts were also discussed. The group also spent some time talking about non-criminal justice interventions such as community
prevention, background checks, protection orders and exclusionary policies.
Some working group participants described a public health intervention developed in Cardiff, Wales. The intervention involves
identification of the locations of violent incidents associated with victims coming to emergency rooms and trauma centers.
Violent hot spots are then targeted with interventions involving multidisciplinary teams delivering component prevention services.
The model is apparently becoming popular in the U.S., with about 20 hospital-based centers currently implementing this strategy
in an effort to reduce violence in communities.
Participants also talked about the nature of change in communities and how it seems that communities must express, in some
way, a readiness to change to reduce problems like firearms violence. Evaluations like PSN show that dynamic relationships
in communities are related to program implementation and to intervention outcomes. There was much discussion around community
readiness for change and implementation of interventions to reduce problems like gun violence. There was general agreement
about the need for further research on dynamics and conditions for change in communities, including community organizing and
preparing communities for change.
There was also discussion regarding the "black-box" methodology typically used in trying to evaluate these interventions and
the need for greater use of qualitative and mixed methods to identify adequately the reasons for results coming from multiple
component programs and complex interventions. Each aspect of programs or strategies should be described and measured as implemented
throughout the process of instigating these interventions to completion of programs and longitudinal follow-up. It was suggested
that research in criminal justice needs to borrow methods from other disciplines in measuring implementation processes and
other dynamics associated with community interventions.
The Chicago Cease Fire program and the Pittsburgh One Vision program were discussed as non-criminal justice interventions
with mixed results. Both programs deployed non-criminal justice staff to intervene in situations that appear likely to result
in violence. Where the Chicago program was able to demonstrate effects in multiple locations, the Pittsburgh program suffered
implementation and research design problems that may have contributed to null findings.
Participants discussed how non-criminal justice interventions in other areas such as health, nutrition and recreation also
appear to have an impact on violence in communities. Many of these efforts are being combined to target multiple outcomes.
There seem to be general consensus that non-criminal justice, community and preventive interventions are worthy of further
study in relationship to firearms violence (as further discussed later in the meeting).
There was also general agreement that criminal justice research on hot spots and place-based interventions should continue,
but research designs and methods should be improved to include measurement of program components, implementation processes
and mechanisms related to explaining outcomes, and discounting alternative explanations for program effects. There also is
a need to assess the sustainability of these interventions once a demonstration is over and project funding has come to an
end. Suggestions for further intervention and policy research ranged from gun courts and other sentencing options to focusing
scarce resources on high-risk individuals and distinct types of firearms violence, and demonstrating outcomes related to community
violence prevention and reduction. There also were suggestions for better research to understand community dynamics and climates,
and optimal ways of approaching communities in the process of preparing for and sustaining change.
Public Health Interventions — David Hemenway
Dr. Hemenway from the Injury Control Research Center and the Youth Violence Prevention Center at Harvard University noted
that no one on the 2005 NRC Firearms and Violence panel was an injury-control professional and few worked directly in public
health. He suggested that the inclusion of a public health representative may have served to broaden the scope of the report
and recommendations resulting from the study.
Dr. Hemenway suggested that a public health perspective is important because it focuses on assets as well as liabilities in
communities. He said that a public health perspective includes intervention through prevention (what can you do before crime),
through a proactive (versus reactive) approach involving the community, with no assessment of fault or blame, and a systems
perspective to preventing problems like firearms violence in the first place.
He provided an example in the decline of auto fatalities. Traffic deaths are often the result of deliberate unlawful behavior
by drivers (speeding, reckless driving, drunk driving). He said that over time policy responses to the problem were implemented
through law enforcement and public health attention to cars, roads and drivers. He suggested that a combination of these types
of factors has resulted in a 90-percent reduction in traffic fatalities over time. Dr. Hemenway stressed that public health
brings together a wide array of interests in targeting social problems and norms related to problems like auto fatalities
and firearms violence.
He then provided examples of how public health data systems have helped us understand problems like firearms violence. Using
data from data collections like the National Violent Death Reporting System and other local surveys, we now know that most
victims of firearms violence are younger than 15 years and are often unintentionally shot by a sibling or other acquaintance.
As it relates to violence, a local survey in Boston has shown a relationship between hours of sleep and aggression among youth.
and that schools with earlier start times appear to have more aggression as well. These kinds of facts help us to understand
problems like firearms violence and develop preventive solutions. He then talked about his book, While We Were Sleeping, which provides further examples of public health success stories.
Dr. Hemenway then discussed research concerning firearms-related suicides and defensive use of firearms with implications
for prevention. He said research suggests a positive relationship between gun ownership and suicide, and a number of facts
indicate preventive interventions may be needed. For instance, although suicide attempts with firearms are most lethal compared
to other means, risk of substitution in suicide is very small. Evidence shows that suicide is often impulsive and risks are
often transitory. Of near-lethal suicide attempts, 70 percent of individuals contemplated doing it for less than an hour,
and fewer than 10 percent attempted it again. Facts like these suggest possible prevention strategies such as means restriction.
He provided examples of a primary prevention program called the Harvard Means Matter Campaign, which is an Internet-based program targeting state health departments. Information for prevention is provided. For instance,
if young people are depressed, removing guns from the home is encouraged. ED-SAFE is another prevention model that involves
some means-restriction interventions including emergency and trauma departments in addition to schools. Another initiative
involves meeting with gunshop owners to find ways they can reduce risk for suicide.
Dr. Hemenway talked about the need for more research and data regarding self-defensive gun use. There is little recent research
in this area beyond what we already know about guns reducing both physical harm and monetary loss in self-defense situations,
and that running away or hiding are better strategies than calling the police. In terms of property loss, having a gun seems
to be effective. Some survey results suggest, however, most uses are viewed as socially undesirable, especially hostile gun
displays, and many are illegal.
Public Health — Discussion
Working group participants discussed issues, questions and gaps related to public health and prevention, firearms and violence
research. Most discussion reflected a general consensus regarding the need for more basic information to better describe gun
violence incidents of all kinds. Basic descriptive information is generally lacking from which interventions could be effectively
developed and tested within and outside the criminal justice system. There was an expressed need for further research on right-to-carry
laws and their progeny, the effect on acquisition of permits and who is carrying weapons. Also needed is more research on
self-defense policies (stand-your-ground and castle laws), what constitutes a threat and how it relates to firearms violence.
It was suggested that the current variety of related policies and statutes being enacted and implemented across the United
States may provide an ongoing policy experiment that should be studied.
Working group participants also identified the need for more research regarding perceptions the general public has about the
relationship between firearms and violence and the reality of the relationship between firearms use and violence. For instance,
it may be useful to closely examine or review a group of incidents such as nonintentional gun accidents, defensive uses and
aggravated assaults to learn more about the dynamics of these situations. It would be useful to examine further highest risk
demography (such as children under the age of 15) within public health approaches to prevention of firearms homicide. It may
be helpful to disaggregate gun crimes and study individual crimes such as domestic assault, armed robbery and aggravated assault/homicide
with a gun.
Day Two — December 1, 2011
Dr. Wellford noted that day two was to include a discussion of gun markets research by Dr. Anthony Braga; Dr. Braga, however,
was unfortunately taken ill at the last minute and could not attend. He said that Dr. Jonathon Caulkins volunteered to provide
some thoughts for discussion based upon his research with drug markets, and Agent Charles Houser agreed to talk briefly about
firearms tracing at the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF).
Dr. Caulkins said that some generalization is possible between research in the areas of drugs and firearms markets. Many aspects
of current firearms markets research are parallel, including such things as categories of access, trafficking and other sources
of illegal guns such as theft. He said that it is interesting to note, for instance, that a third of all guns used in homicide
are acquired illegally. Dr. Caulkins believes that the market perspective is valuable in the field of firearms and violence
research. His own work in drug markets illustrates the value of monitoring aspects like price, for example, when studying
any illicit market. He warned that firearms are durable goods and looking at simple and isolated variables such as quantity
probably biases what can be learned from such research. Dr. Caulkins suggests firearms research needs to provide a more complete
picture or description of transactions including chain of supply and life cycle. He suggests it may be more productive to
study the issue prospectively rather than retrospectively. More research is needed to describe the life cycle of firearm ownership
as well as life cycle of the firearm. More aspects such as inventory, turnover and history also need to be measured to better
describe markets. Dr. Caulkins suggested that greater differentiation is needed regarding types of crimes committed with guns
as well as the many types of situations in which firearms are used.
Special Agent Charles Houser briefly discussed gun tracing by ATF. As chief of the division, Special Agent Houser oversees
a program implemented in 1988, which has grown from 48,000 tracing requests in the first year to more than 300,000 last year.
Tracing data are added value to an investigation providing links between suspects and crimes. Tracing increasingly contributes
to investigations concerning trafficking and illicit distribution of firearms worldwide. Computerization has contributed greatly
to the program, and the process recently has become more efficient in converting to an Internet-based information system.
Special Agent Houser said ATF receives about 1,400 tracing requests every day, although there are still problems presented
in current tracing technology. For instance, misidentification of weapons still remains a basic problem. A serial number alone
is not a unique identifier of a firearm. Other identifiers are necessary, and most failed submissions are because the firearm
has not been adequately identified. He said that an Internet-based system has increased data availability and further sharing
of information among law enforcement agencies engaged in criminal investigations. Research on markets, supply and demand is
very useful in practice, and further research is needed as firearms are related to violence in many ways all over the world.
Emerging Issues in Methods and Data Collection — John Pepper
Dr. John Pepper from the University of Virginia provided brief comments regarding the working group discussion related to
emerging issues concerning methods and data collection. Lack of good data continues to be the biggest problem in research
on firearms violence, as it is in much of criminal justice research. Separate issues involve whether needed research can be
productive given current methodologies, and what methodological issues need to be addressed. But, the biggest problem area
seems to be the lack of valid and reliable data. He suggested we address how to feasibly acquire and provide the necessary
resources to collect better data. He suggested that more research on perceptions of the relationship between firearms use
and violence may be useful, as would data on implementation, how different regulations are enforced, and how the criminal
justice system implements laws and regulations related to firearms. Mixed-methods research on perceptions about firearms and
implementation may go a long way to help us better describe processes and dynamic systems involved in firearms violence.
Dr. Pepper said that further use of ecological studies may be of limited utility and suggested that it may be more useful
to promote case-control studies that particularly attend to issues of validity. Lastly, he said much more is needed in the
development of theory about firearms use and violence. In a world of bad data, one option may be to plow forward and come
up with answers, but it may be more productive to spend more time developing more theory as we develop better measurements
Discussion ensued regarding firearms markets and tracing systems research, including issues concerning valid and reliable
ways of measuring market-based variables such as price, supply and demand, differences and similarities, overlaps between
legal and illegal markets, and firearms as currency in drugs and other organized crime. There was general agreement regarding
the need for research to look at separate and distinct areas or "silos" of firearms violence like suicide, crime types, crimes
of passion versus planned crimes and self-defensive use.

 Consistent with the theme of the National Research Council's report on firearms and violence (Wellford, Petrie and Pepper,
2005), the working group's analysis of research needs recognized the limits articulated in the Supreme Court's Heller decision
(554 U.S. 570, 2008). Nothing in the working group's discussion or in its analysis of research needs requires or anticipates
any changes in the current interpretation of the meaning of the Second Amendment for reducing gun-related crime. Each of the
topics discussed below is consistent with the individual right to possess firearms that has been articulated by the Court.
