I see the streets. Go to 6th and Market now, or 16th and Mission, both streets have tents that sell hard drugs. Every night, there are a lot of things going on there.
Who does even attempt to stop them? I lived in multiple countries, and the toleration I see here is just incredible. I saw those who sell and use heroins, and we (me and bunch of coworkers) just passed them.
Just a regular day. I don't believe your numbers. Plus; I believe, this entire business is a way to keep the poor classes as poor. Go read about Hasan Sabbah.
