The way to solve the problem in the BART stations is simple. You go in there with cops, you arrest every single bum in there on drug charges. Do it weekly, they'll go somewhere else. Then you do it up on the street until they get the fuck out of there too. The reason they don't do this is because the jails are all full already with beaners. Like to the fucking brim. A solution would be tent city prisons like Sheriff Joe did in Arizona. Or DEPORT criminal illegals to reduce some of the overfilling.
Instead, what the Democrat retards in CA do is just say less things are crimes. Like drug use is pretty much just Hamsterdam all over the city now. And property/vehicle crime under 1k is just A-OK, no problem to commit. 
Then liberal retards pretend like they can't figure out why the city is just complete shit.
