That's from your "Vietnam Created Charles Manson" page in the playbook. I'm less than astonished.
I work with a guy who was in law enforcement in Philly up unti a couple of years ago.
I think there are many more factors that were present well before the war in Iraq such as -
crack
gangs
single mom welfare villages
gangsta rap mentality among youth
a joke of a juvenile justice system
public housing (lets put all of the above into a small area)
I would also bet there are now more men between the ages of 16-24.
The mayor should put the blame on himself and others who support the welfare state.
