the defund movement do tend to be supported by those who are actually doing the work or are adjacent to it.
You say that, but what I’ve realistically observed is people with little enough insight into the actual issue that they wind up perpetrating a lot of functional hypocrisy / double-think. Most of of the people working these positions in my area are black because that’s just the demographics of the area, so they’ll see these videos of cops killing black people and SAY ACAB or defund the police, but in the same shift I’ll watch them turn around and say some of the exact same shit to patients that these cops said to that poor schizophrenic lady (“don’t you dare or I’ll ___” or something similar but in this case the blank is fortunately something non-fatal like forced medication or restraints).
Most people lack the insight to realize that their thought patterns are the same as the people doing these things, because they think THEY had a good reason to say it because it made sense to them in the context of what was happening to them personally and the patient was ok in the end. When all they see is the video they don’t see the other frustrating or situationally intimidating things this person did before their death (and it’s not that they deserved it, it’s that you have to control whole situations to stop this kind of thing, intervening in the last five minutes is faaar too late). That video was actually an excellent example of this; I even saw someone point out that they never should have let her hold the kettle in the first place; one of the officers should have recognized that she was in crisis and offered to get the kettle FOR her. She should never have been allowed the opportunity to pick up the improvised weapon in the first place because it should have been obvious to them that she could not control herself in that moment.
Few people just snap and kill somebody in under a few seconds, its the fact that they’re ever letting shit get that far in the first place is the actual core issue here. It’s incredibly easy to look at a single video and say “I would never” but part of my talent for handling these situations is understanding what causes a person to get to that point. I’m the person who notices my coworkers getting frustrated and taps them out because I’ve noticed that it’s always the martyrs who say “I would never” that fail to monitor and intervene with their own frustration levels and who don’t account for what a person not in control of themselves is actually capable of that wind up doing the most fucked up shit.
