People in between “cannot manage own life” and “imminent danger to self and others” are a tricky proposition for the mental health system. It only takes a handful of such people wandering around your city center continuously (seriously, it’s the same dozen faces over and over in SF) to completely change the kind of place it is.
I didn't say kidnap and torture them like we did in the 70s. I said give them mental healthcare and housing.
People don't become junkies overnight, and a building full of single bed sized lockable (from the inside) rooms available to anyone without stable housing (without fear of the salvation army taking them off of HRT or abusing them) with a few social workers and mediators to teach those skills, a doctor, a vocational educator, and a therapist on staff 24/7 is both cheaper than policing and jail, and would go a long, long, long way towards preventing these problems in the first place.
There's absolutely no reason not to do this. It's cheaper up front than policing. It saves the same amount again on cleanup and maintenance of public spaces. It saves many times the amount of money again on reduction of crime and insurance. And it provides a portion again in people that become productive tax payers
For the ones that have already fallen to the bottom of the hole you need something more, but surely if it's doing so much damage to the entire city that out of the 300 billion gdp, the inhabitants can afford four dozen social workers and an apartment block to do nothing but try to find a way to help them.
The idea that this is even a question in the wealthiest place on earth is mindbogglingly callous and evil, and a sign of a very very sick and antisocial society that has nothing to do with the people that fell through the cracks.
Then don't manage. Serve and support. Start by bringing a sandwich, a coffee and a smoke and listening for an hour every day, not by shoving them in a cell.
Yes, it's expensive, but if it is -- as people here and elsewhere say over and over again -- making an entire area of a city uninhabitable and causing millions in damage and enforcement costs then surely it's worth the cost? Why do people seem to constantly favour being callous and cruel over even being selfish, let alone humane?
