Hmmm, there were two muggings in Noe Valley at the corner of Jersey and Noe when I was there. Yea, I know, anecdote. I heard one of them. It happened within 100 feet of my apartment at the corner. At the time I just thought it was some kids but found out the next day it was a mugging.

Had my bike stolen from my garage there. Garage was closed.

Also had 4 Japanese co-workers come for GDC and get mugged on Market between 6th and 7th. Broken teeth, concussions.

Some friends of friends moved into an apartment in the mission near 20th and Harrison. They got robbed as they were carrying their boxes up the stairs to their new apartment. They didn't stay in SF.

I don't consider SF "great"
