If you are going stereotype offensively for shock value, then you damn well better have the statistics to back yourself up.

In 2005 in the US, there were 7 times more black homicide offenders than whites: http://bjs.ojp.usdoj.gov/content/homicide/tables/oracetab.cf...

At first glance, that may provide some evidence for your theory.

However, an alternate theory that I prefer could be stated something there is an inverse relationship between income and likelyhood of committing violent crime.

http://www.census.gov/compendia/statab/2010/tables/10s0699.p... shows that Black families are about 3 times as likely as whites to be below the poverty line. An average black household size is 2.7 (http://www.housingbubblebust.com/PopHsgRates/AllStatesHouseH...).

2.7 * 3 = 8.1, which is actually less than the 7 times offending rate cited above. (Yeah, I know there are some pretty big assumptions in that big of math. Still, the point remains that there is a real relationship between poverty and crime rates)
