Violent Crime on the Decline

A DOJ data sheet shows a dramatic decrease in violent crime in recent years. Up until 1994, it held pretty steady around 45-50 violent crimes per 1000 people age 12 and over. By 2004 it was down to 21. That's a remarkable decrease and leads me to wonder what has been responsible for this decrease? Increased police presence? Increased penalties for offenders? Some sort of social change?

While I don't really believe that the rise of video games has caused a decrease in violent crimes, it is an interesting correlation. This seems to directly contradict those who try to draw a causation link between violent video games and violent crime. [story via Digg]
