Plus, I'd suggest that most U.S. robberies aren't street crime against foreigners (or even citizens): they're car, house, or business break-ins when the occupants are (usually) not there. Not that this is any better than roving hordes of pickpockets, but it's not something a tourist has to worry about walking around downtown San Francisco.
