YOU just denied they got justice. Public opinion is all BLACKS are guilty. Even when the video and evidence show otherwise. Yes there are cases where it is so blatant with video to back it up but without that it is impossible.
So what was your intent on bringing up those cases? they got justice? or they didn't? I repeat only a fair jury with people representing that community without racial profiling can get justice. An all white jury thinks guilty before proven innocent. Did you notice in 2 of those cases the beatings and arrests were so blatant racist even as they KNEW what they were doing.
Demand car/body cams. Demand no mistaken laps in video. Demand Police with abusive behavior lose their jobs permanently and don't get rehired. Well over 50% of fired cops get rehired.
