Question: In the mid-1970s, the state of New Jersey announced a "Safe and Clean Neighborhoods Program," designed to improve the quality of community life in twenty-eight cities. As part of that program, the state provided money to help cities take police officers out of their patrol cars and assign them to walking beats. Five years after the program started, the Police Foundation, in Washington, DC, published an evaluation of the foot-patrol project. What did this evaluation find? What was the significance?
