Violent crimes are scary for blacks.
Couple of interesting things. Check out the Alcohol related offenses and gambling.
There are definitely environmental/socio economic factors in play here.
End of the day there are people of all races that suck and there are people of all races that do not suck.
I view Imus comment as supporting a lot of the stereotypes that people have.
You ever hear that one, "All Poodles are dogs, but not all dogs are Poodles"
IMHO Imus and those that use those kinds of examples are trying to say "Some criminals are Black therefore Blacks are criminals".
