I've lived in Toronto, SF and Sao Paulo. In 18 years living in Sao Paulo, I've witnessed one gun-related incident and was victim of robbery once (I lived near Heliopolis, one of the largest slums in the city). In 18 years living in Toronto, I was involved in zero. In my first 2 years in SF, I was harassed twice and witnessed retail theft 2 times. SF is "not bad" in the sense that you won't get shot in the face. It is however quite bad in the sense that the amount of petty crime is so off the charts that you can't even compile accurate statistics because security personnel at retail stores don't even bother reporting it anymore. A few months ago, I witnessed another theft in inner Richmond (one of the nicer neighbourhoods), the security guy did a half-ass attempt at running after the guy but gave up and came towards the customer support desk I was at. I asked if that was common, and the security guy literally just shrugs.
