So there's often more factors there. As far as getting stopped more by LE, absolutely true. Because systematic racism or because more blacks live in high crime areas, high crime areas have more cops assigned, and more cops per capita in a given area logically results in more opportunities to be stopped by the police for the same sort of infractions?
How can you simultaneously argue that 'perps get less time for killing them' and 'prison sentences' when the vast majority of black victim cases are also black suspect cases. Does jury sympathy play in? Do folks find it more socially acceptable to kill a drug dealer then a doctor who's house you broke into? Yup, they do. Do plea bargains consider the strength of the case and do how cooperative and sympathetic (as in not criminals engaged in criminal activity at the time) consider that? Yup. I've had juries let whites and blacks go who OBVIOUSLY shot or stabbed somebody illegally but the victim was such a shit bag or was engaged in criminal activity and the jury figured they had it coming.
Not everything that happens to a black person is BECAUSE they are black.
