Résumé
"...Police Executive Research Forum (PERF) undertook a national study of gun violence prevention efforts by local police in urban jurisdictions. The study’s objectives were to: 1) to describe the range, scope, and prevalence of police efforts to reduce gun violence; 2) to assess which practices are most effective, both generally and in combination with different gun laws; and 3) to determine how these efforts can be improved."--Pages 1-2.
