UW study on race and violence

• The subjects in the studies, who were instructed
  to shoot only when the human targets in the game
  were armed, made more errors when confronted by
  images of black men carrying objects like
  cellphones or cameras than when faced with
  similarly unarmed white men. The participants,
  who in all but one study were primarily white,
  were also quicker to fire on black men with guns
  than on white men with guns.
