It isn't preemptive to see cops as our enemy, for they're already taught to view the public as an enemy. The reform we need isn't even what gets discussed by anybody who wants to "work" with police.

Public safety needs to be gutted and rebuilt from the ground up, with cops only handling situations where someone might need to die. There is no non-lethal violence. Any instance of cops using any form of violence carries the risk of someone dying. We shouldn't expect them to be anything but violence machines; a last resort to any issue, not part of a front line.

If their unions don't hate you, you're never gonna actually accomplish anything. It's not a good strategy to ally with people who get upset at being anti-cop. In the US, politicians who say "fuck the police" are better off than any respectability politician. We've heard nothing but meaningless platitudes for years, and people are tired of it. The "safe" politicians have provided no safety, and people are too scared to trust them any longer.
