A rise in crime

Personally I think Katrina and meth have something to do with it but Tom Barnett might have it, specifically

the three-strikes and other harsh-penalty laws of the previous decade had surged the prison population, but soon the number of ex-cons being released (about 600k, if I remember) would surpass the number of new cons going in (about 500k). A simple prediction: urban crime was going to go up all across America.

Food for thought.
