Mobs are not the law.
Seems like that would embolden mobs to destroy whatever they want. Doesn't seem like an intelligent or sustainable strategy.
...but the unfortunate reality is that allowing mobs to destroy property become a feedback loop because they then realize that mobs can destroy anything they like with impunity.
That's no way to run a civilization.
I'm curious how many protestors or rioters keep their phones on them (with location/COVID apps or otherwise.) Even if they don't, plenty of others are taking the videos.
