Requesters repeatedly ask for the best source of criminological evaluations on a variety of crime-related issues and the answer is CrimeSolutions.Gov.
Please watch the attached YouTube video for an overview, then proceed to https://www.crimesolutions.gov/ and read the “About” section before proceeding.
CrimeSolutions.Gov is the best methodologically correct (well done) compilation of crime-related research with easy to read overviews. There are three resulting categories: effective, promising, and no effects.
The Office of Justice Programs of the US Department of Justice took the lead in creating this long-overdue service. We within the criminal justice and criminological communities are in their debt.
