Not the OP, but while I was living in SF I saw drugs sold on the street, needles left on the ground in public parks, people stealing registration stickers off license plates, smashed car windows, people blocking sidewalks and harassing pedestrians, ridiculously unsafe driving (e.g. running reds including cops, ppl cutting across three lanes to make a left from the right lane, etc), guests who visited me were flashed by randos, a dude was jerking into a newspaper box by the BART, neighbors would smoke inside nonsmoking apartments with shared ventilation, etc.
I'd move back again for work if I have to, but it would take a lot of $$$$ to convince me.
