In New York many decades ago, murder rates on the Metro system were drastically reduced by concentrating on the little things - like people jumping over ticket barriers, and graffiti on trains (Tipping Point, Malcolm Gladwell).
If I remember correctly from the book Freakonomics, you will find that the real reason the murder rate dropped was because the abortion lows were eased about 18 years prior to the "zero tolerance" policing. In other words the nice people likely to give birth to a criminal, had abortions and so the crime rate dropped
