Remove them. It is an abuse of the commons that creates a vicious cycle that will only exacerbate the problem. And for your next question, San Fran already spends $141k per year per homeless person. That’s 7x LA. It isn’t working because of the lack of accountability and oversight in the use of those funds and San Fran’s lax (even favorable treatment) of public drug use, public camping, and general lawlessness. Send them to a shelter, treatment, or jail. “Harm reduction” doesn’t work. Full stop.
