The worry about police violence is really misplaced worry about the effects of a broken justice system. It's not just that police kill unarmed, non-violent black teens. It's that "they" (the justice system as a whole) also lock people up for non-violent drug offenses, put a felony on their record, condemning them to a life without job opportunities. Then "they" kick them out of their homes when they're late on their rent. Then they forcibly break up homeless encampments so people without homes can never feel safe or settled or have somewhere to sleep.

Police shootings are just a potent symbol for a much larger issue with the Justice System. The problem is that conversations about complex systemic issues become circular and conversations about symbols often don't.
