A nice homage to John Timoney in the New York Times. Among other things:
In 1972, New York officers fired 2,510 bullets and killed 66 people. By 2014, there were 288 shots fired and eight people killed.
What happened? Mr. Timoney said that in 1972, the department put restrictions on when officers should shoot their weapons. Within a year, officers were firing about half as many shots.
