Malach,
2 issues as I see it, from “read[ing] about it in the news.”
1. Some folks may be not be dangerous to others, but are not capable of taking care of themselves. Thus is it “humane” to let them live on the streets and through their open air spreading of their urine and feces, set up a health danger to others?
2. The “urban renewal” of the 1950’s and 60’s that demolished housing that was very low cost to individuals and thus denied them places to live?
And, from how you typed your answer, you and those “trying” with you were unable to find solutions?
