The evidence suggests that if there is police racial bias in arrests it is negligible. Victim and witness surveys show that police arrest violent criminals in close proportion to the rates at which criminals of different races commit violent crimes.
Both violent and non*violent crime has been declining in the United States since a high in 1993. 2015 saw a disturbing rise in murder in major American cities that some observers associated with depolicing” in response to intense media and public scrutiny of police activity.
Crime rates
There are dramatic race differences in crime rates. Asians have the lowest rates, followed by whites, and then Hispanics. Blacks have notably high crime rates. This pattern holds true for virtually all crime categories and for virtually all age groups.
In 2013, a black was six times more likely than a non*black to commit murder, and 12 times more likely to murder someone of another race than to be murdered by someone of another race.
Interracial crime
In 2013, of the approximately 660,000 crimes of interracial violence that involved blacks and whites, blacks were the perpetrators 85 percent of the time. This meant a black person was 27 times more likely to attack a white person than vice versa. A Hispanic was eight times more likely to attack a white person than vice versa.
