Blacks are seven times more likely than people of other races to commit murder, and eight times more likely to commit robbery.
Blacks are three times more likely to use a hand gun, and twice more likely to use a knife.
Hispanics commit three times more violent crimes than whites, but the statistics are nebulous because sometimes they are classified as white, so it could be far higher.
The best indicator of violent crime levels in an area is the percent of the population that is black and Hispanic. Blacks are 39 times more likely to commit a violent crime against whites then vice versa, and 136 times more likely to commit a robbery. Forty-five percent of black crime is against whites, 43 against other blacks, and 10 percent against Hispanic.
