My understanding is that police reform is impossible because the system is so corrupt there's no way to make it happen. I've seen many accounts of the good cops quitting because they got harassed out.
Perhaps we should instead focus on messaging for "are the police above the law?" and if not what does that look like? And "why should taxpayers pay for police fuck ups?"
I dunno, just tossing stuff out there. But it's clear that policing is broken and needs fixing, and that won't happen until there's enough unity in wanting to see it happen.
