In 2005 the city of Los Angeles had 488 homicides. The year before that, 480. So far this year we're down to 249.
Compare this to 1995, where we had 849. It dropped substantially (Isn't that when the truce between Grape Street and Nickerson Gardens went into effect?) and then shot back up in the late 90's to 2004. It's been dropping steadily since then.
If we keep up this trend we could see fewer than 400 murders in the city this year. Somebody must be doing something right.
