At the 0:10s mark of the video, the ex-stabber makes a move on the mayor and gets in the bodyguard's face, trading words. The SFChronicle reporter noted that critical detail you've overlooked.
Seeing the threat depends on one's bias. The mob that hates police and/or the mayor (he's jewish, billionaire, etc) can't see it, because all violence is supposedly the system's fault. Verbal threats are only real if the system does it.
For me, I lived next to the Tenderloin for two years & was threatened at knife-point by a nearby homeless. I think the risk warrants the shove. Maybe if the bodyguard hadn't shoved, the mayor would be fine. Or maybe the mob would have been much, much happier that day.
