The National Review has a good article by David French which dissects and debunks many of the anti-police narrative put forward by the Washington Post . It’s worth your time to read it.
Crime doesn’t break down on neat, proportionate demographic lines. Criminals are overwhelmingly male (police killed very few women this year, but no one argues that law enforcement is sexist), and violent criminals are disproportionately black. In fact, blacks “commit homicide at close to eight times the rate of whites and Hispanics combined.” Even worse, “among males between the ages of 14 and 17, the interracial homicide commission gap is nearly tenfold.” In 2014, for example, while black Americans constituted only about 13 percent of the population, they represented a majority of the homicide and robbery arrests. 82 percent of all gun deaths in the black community are from homicide. For whites, 77 percent of gun deaths are suicides.
