On a larger scale, it'll take a lot more than this to destabilize our society. I know it's not an equal comparison, but I'm hopeful that post-9/11 "come togetherness" will emerge from this in some way.
Unrelated: Super bad luck to the guy that brought his AR-15 to the protest as a 2A demonstration. You definitely don't want to be that guy when someone else starts shooting. Good thing that was cleared up with police in a peaceful manner. Wrong place, wrong time. Turned himself in to police the minute he became a "person of interest"
Considering the circumstances, big kudos to the police that it was cleared up in a peaceful manner.
