This ignores a lot of context - particularly the fact that many of these policies were widely supported by both the black community and law enforcement until maybe midway through the last decade. In the 90s, these were the "common sense" reforms we all bemoan aren't getting passed today. Not to mention the fact that Clinton is actively running a campaign specifically decrying these policies and acknowledging their failure. Sanders doesn't seem to be anywhere on this issue, and I'm not sure why he should "deserve" the vote any more than Hillary.
Did you read the article? If you did you would see that she brought up many of those points.
