Leave them where?
Part of the issue is that those who do not want to follow the requirements of provided housing like no drugs, pets, shopping carts, curfews have no where to go except public streets or parks and they are making those areas unsafe and unusual for others.
The issue is can they be forced into housing, especially housing with the rules? Can they be arrested for littering, for begging outside businesses? Can they be rounded up for their own safety? We do that in my city when it is deadly cold outside, and they don’t like it at all. When good Samaritans hang mittens and scarves on the trees in the civic center park, is that against the law?
Providing housing for those who want help is the easy part, but the question is can housing be forced on people.
