I'm having trouble parsing who you think is the wronged party here, but to be clear this fire official was going around bear spraying random innocuous homeless people before one of his victims fought back and beat him up.

It's not by accident that everyone in my immediate social circle carries a weapon of some kind now. The existential threat from both the state and other citizens grows daily.
It doesn't help that moderation is almost non-existent, aside from when VC's get put under blast, or when . Asking for sources for ridiculous comments (eg: Dropbox laid off people in order of performance) gets flagged, then removed, but off-topic humor in bad taste remains.
But breakdown of law, order and general societal cohesion invites this kind of behaviour. It's still the perpetrator's fault, but conditions are made so that these people are more likely to lash out.
