I dunno, for me, a gay/queer fellow, I can't support an organisation (the police) who had as part of their literal job to arrest folks for doing gay stuff. When I learned about the harm cops cause to communities that aren't mine (Black communities, Indigenous communities) it just sealed it for me. ACAB, all means all, etc.
If I get serial killed, I already know the cops' investment in finding the killer is directly proportional to my economic status and proximity to power, so.
