Help is needed for the homeless but also training on how to live. They leave the place a mess. Even if they were given a place to live they'd be kicked out because of not keeping the place clean. Not all but most.
This is part of the hush hush strategy of cities like SF. Homeless, street dwellers, public bathroom dumpers, and drug addicts all keep City workers employed with Federal grants to “combat homelessness.” No longer really much of a secret. The homeless continue to be homeless but they get cleaned up after and offices are abuzz with social workers trying to figure out how to save them.
The problem is that these people don't want to live with other people. So a congregate shelter is innapropriate for a lot of this population. The Honu doesn't help mentally ill people.
