Although this study found there was some racial bias when it came to police using force to arrest a suspect, the study found there was no racial bias when it actually came to police shooting suspects. So according to this study, the whole narrative we get from the media, Obama, and from Black Lives Matter that the police are disproportionately shooting black people, is false.
