Most homeless people are down on their luck and really need support. Affordable housing, job training and placement programs, food, and medical care can really help these people. I don’t have any problem with this majority of the homeless population.
A small percentage of homeless are insane, whether due to mental health problems/drugs/some combination. These are the people causing problems. They cannot be left to destroy themselves and society around them. We need mandatory care for these people for them to live with dignity. It is not compassionate to throw them on the streets and ignore them. We need asylums for this subset, like we had until Reagan closed them all.
