No cop has ever been held accountable for whatever bullshit they pull when they're in riot gear. They're basically anonymous and the worst that will happen is a civil settlement with the city (which won't even come out of the police budget!).
Have you seen the damage caused by their bullets? It's like using frozen paintballs, at the high end of allowed PSI, but the size of a golf ball. LA civilians rn are under hostile armed force. They need an armed* resistance to take out the members of the police that do not act as police. They do not get punished. They just get deployed again.
*I know this is difficult. Non lethal weapons are harder to obtain than lethals, and the moment the resistance use lead is the moment the invading army do too.
