Kill City?

The following link was posted to rec.arts.mystery newsgroup by Ian.
It's a graphic map of the homicides committed in New York City between 2003 - 2009. They number 3,402; an average of 540 a year.

For someone like me who comes from a small place with a population of about 70,000 which has a homicide rate you could count on the fingers of one hand each year, this is just mind-boggling.

You can mouse-over the map and read the statistics of each homicide. The age and ethnicity of the victim and perpetrator, the motive and the weapon used.
