In 2022, there were over 1 million vacant houses just in the state of New York.
Vacant does not mean government owned. Homeowners can do whatever they want with their homes, including leaving them vacant. So again, what free housing would be used to house all these people? Also the way you describe this, it would be ripe for abuse by people who just want a free house wouldn't it? Just don't pay your rent and get taken away to be given a free house and food and all your bills paid!
If there are over a MILLION vacant houses, and 350k (or slighty more) homeless people, what the fuck are we doing?
See above.
It doesn't state that at all. That's your poor reading and comprehension skills at play.
The whole point of this is that now instead of police being dispatched as first responders, it will be unarmed trained mental health professionals. So it's the exact opposite of what you're saying it is.
