The courts protect FBI and police. [0] Impossible to get a real win from a lawsuit. Getting money is not a real win. [1] No changes will be made. The dude who got murdered by police and caused a riot of criminals stealing and burning down buildings, not even that caused the police to change.
I should add a white person got killed the same way before that. No riots. No news. No screaming crying people in the streets demanding justice. No change then either. The family of that person didn't even get money from it.
