I think it has less to do with race and more to do with economic status.  Naturally, you will see more crime in poverty stricken areas.  And most of the perpetrators are the poor. 

I am sure you will see less of racial bias when you go up the socio-economic ladder.  Points to look at would be: what proportion of blacks do you see committing white collar crime and what is the ratio among different races in that strata.
