Grim Statistics

Demographer Heather Mac Donald writing for National Review Looks at the FBI statistics on who murders whom in the U.S., by race. It turns out what you suspect to be true is in fact true. Whites are much more likely to be killed by blacks than vice versa. She adds:

In 2013, blacks made up 42 percent of all cop killers whose race was known.

In other words, 13 percent of the population does four of every ten cop murders, a statistic which could explain cops paying extra attention to blacks. It's the same reason people are more wary of pit bulls and Rottweilers than they are of poodles and golden retrievers - different risk factors.
