Easy - if the white population is 62% and the black population is 13% it's easy to figure out why the black population is killed by police as a percentage of police killings. Just like the populations of prisons are over represented by black and Latino men and women. Why? The major reason is over policing of their neighborhoods. Drugs being the major reason. Now more white people use drugs and there are more white people selling drugs yet why are they not arrested at the same rates at a minimum? Could it be better legal representation? Could it be much much less policing? Could it be white people can get many of their drugs legally through pharmaceuticals?
