“blacks while only about 12% of the population account for about 80-85% of the violent crimes...”
Keep in mind that of the 12% approximately 1/2 are males. So most of the violent crimes are committed by just 3% of the population.

This article links to the actual data; the key number is that a white woman is 12x more likely to be killed by a black partner then by a white one.
