Overview of the Program

Established in 2014 through a partnership between NIJ and the International Association of Chiefs of Police (IACP), the Law Enforcement Advancing Data and Science (LEADS) Program develops the research capacity of mid-career law enforcement personnel who are committed to advancing and integrating science into law enforcement policies and practice. To accomplish this, merit-based scholarships are competitively awarded to mid-rank officers from agencies of any size and executives from small agencies who have effectively infused research into policy development within their agencies.

Research is a valuable tool for law enforcement agencies. This program aims to identify and nurture the next generation of law enforcement leadership through encouraging the use of evidence-based research to advance criminal justice.

Captain Thorpe developed the Sarasota County Sheriff’s Office current program of "Intelligence 2 Action," which places a strong emphasis on analysis-supported response to crime and hazards. The collaboration with other agencies has resulted in the area law enforcement exchange, or "ALEX" program, that has considerably enhanced information and intelligence sharing among local, state and federal law enforcement in the southwest region of Florida. Captain Thorpe takes a special interest in the effect of repeat or "prolific" offenders on crime in a community. His research in this area led to his pursuit of involvement in the LEADS program. The LEADS program has become a quick success in promoting the importance of academic/practitioner relationships in building solid and efficient practices for daily policing in our nation. As this program continues, Captain Thorpe suspects the benefits will become something to behold; but the networking relationships among the LEADS scholars and their new research contacts have already proven to be exceptional.
