I'd say it has everything to do with the current state of affairs in SF. I don't think it's the post-apocalyptic hellhole that many make it out to be but property crime here is really out of hand.
Police don't take anything less than a stabbing serious (I had my motorcycle stolen and the police came by 6 hours after I called them and then jetted off to stabbing within 2 minutes of arriving). I called the police 6 times in the first few years I was here, every time they arrived at least an hour later and provided absolutely no help. Last time my motorcycle was stolen and I found the guy parting it out on Craigslist, they were of zero help. I just don't bother anymore.
One of my friends that lives on Capp street witnessed burglars in an obviously stolen car with stolen goods, divvying up those goods in the middle of the night, and then went into a neighboring house. My friend was on the phone with the police as it was happening and they recorded the whole ordeal on video. Police slowly cruised by an hour later and that was that.
I understand that jailing people won't magically fix all of our issues, but the approach we have been taking is obviously not working. We need to try something new. I personally like the idea of hiring more police and getting them to constantly patrol their beat so that they are in-tune with their community and the community feels the police presence. Because at the moment, parts of SF, especially the Mission, feel lawless as fuck.
