I worked in the tenderloin - so plenty of open air drug dealing (not a huge problem) as well as random attacks on people (a problem). My roommate was jumped and beaten near our place - very disruptive to his life in general.
I actually caught folks who had stolen my car, good response by police, got them in the car too driving it. I asked, if I pressed charges, what's the consequence. A few days in jail if I was lucky and wanted to spend years pursuing the case - these would be guys who I'd then have a beef with in my neighborhood.
I didn't carry a gun or knife and just didn't want to beef with the dudes hanging out. At some point you are like, is this worth it? As you get older, have kids - you just want to let you kid play. Where I am now the kids can play on their own with neighbors on the street - no worries. Much nicer in my view.
I'd move back again for work if I have to, but it would take a lot of $$$$ to convince me.
More shit than I've ever seen on any city streets. Every doorway, tree, and wall reeks of piss. It's no way to live.
Not saying that's ok, just that SF is hardly unique in that regard.

Based on this thread, there's a lot going on that people are lucky enough not to notice, or choose not to notice, but it definitely makes SF a risky choice for businesses. I probably fared as well as I did because I'm tall and didn't go out much without other people with me.
Sigh. NM, c'mon, we can do better. Can't we?
Chicago is still a very segregated city, and the north side is relatively safe. San Francisco is small, and while the problem areas concentrate around Civic Center / Tenderloin / SOMA, literally everything else is in walking distance, so petty property crime is quite widespread.
