re: #649 garhighway

Interesting stuff. The declines in violent crime rates over time are striking (comparing 1990 to 2005):

NYC: down 71%
CHI: down 58%
LA: down 65%
US as a whole: down 35%

That would seem to indicate that some crime was moving to the suburbs and rural areas. Could that be related to Meth vs. Crack user demographics?
