Crime Prevention Research Center
The Crime Prevention Research Center (CPRC) is a research and education organization dedicated to conducting academic quality research on the relationship between laws regulating the ownership or use of guns, crime, and public safety; educating the public on the results of such research; and supporting other organizations, projects, and initiatives that are organized and operated for similar purposes. It has 501(C)(3) status, and does not accept donations from gun or ammunition makers or organizations such as the NRA or any other organizations involved in the gun control debate on either side of the issue. Our goal is to provide an objective and accurate scientific evaluation of both the costs and benefits of gun ownership as well as policing activities.
