Prisons

You could argue that the outcome will be a large number of people with mental health issues crammed into a massively overburdened prison system with almost no hope of ever getting out. (Where would they go? Back to being homeless and thus getting arrested again.) 

We’ve tried that with serious mental illness, and it doesn’t work. It fixes nothing unless you think lots of people with mental health issues dying in prison is the answer. I prefer that most of us are not that callous and uncaring. But most of us aren’t writing these laws and upholding them. That’s for the elite few with power, and I’m not as convinced they would care about anyone with a mental health struggle because they surely don’t do much to provide resources and assistance to struggling people.
