SF attitudes towards certain behaviors make hard to do what most cities do, which is arrest these people and make them go somewhere out of sight.

There are cleaning staff going through the area cleaning stuff up. But people still are doing their crap and the laws are unenforced because of those political reasons.

I also think SF police & the city decided the tenderloin was the homeless containment zone long time ago with SROs being there. That is also where the civic center station is.
