And if all those people smoke pot in SF as you alluded to, and it makes them crazy, why is the murder rate so low compared to other cities?

Again, yes, we have a lot of crazy potheads in S.F., and, yes, a lot of their mental illness is caused by pot. They're not all violent but some are. They're not all armed, but a few are. I'm not saying that all pot users are paranoid/delusional. Most of them aren't but a few are. Like the pot head who shot Chris Kyle. Like the pot head who shot Gabby Giffords.

I'm not sure why this is so hard to understand (but then again pot does diminish reasoning). If I said that 90% of folks with lung cancer are tobacco smokers (true), it wouldn't be the same as saying that 90% of tobacco smokers have lung cancer (untrue).
