You can still argue your assertion further: you seem to be declaring that race (and not class) is the driver for crime. Race and class (in America) are strongly linked that when a person declares one thing (and not the other) as the cause, it tells you a lot about the person.

It looks to me like race matters more than class. Poor whites and hispanics don't commit nearly as much crime as black citizens, even though they are numerically greater. 6% of the US population (black males) commits 53% of the murder, more than the other 94% of the population combined.

There is something uniquely wrong in the black American community. Whites who notice it are called "racist". Blacks who notice it (like Bill Cosby) are called race-traitors or Uncle Toms. So nobody much cares about addressing anti-social behavior, because it simply cannot be discussed.
