You would have to compare the reporting rate also. No idea what it might be in Orlando. In San Francisco I expect it's now low: I'm at two physical assaults in San Francisco and there was no point in reporting either (countless verbal but that's not "violent crime" classification). And the recent (news) reporting on robbery makes it doubtful that much of it gets (police) reported either.
Then again what surrounds Moscone is mostly not "violent crime" as per this classification.

Edit: clarified news vs police reporting
