The fact he was there was an act of vigilantism. Haven’t we had enough people getting killed over nothing? I have.
A mob burning down property and hurting people, is not "nothing".
You say that you have had enough of people dying, yet you seem to support the mob.
You need to understand this. As you use and/or escalate violence, those you target will do the same.
Unless your plan is to get US to a point of say, Soviet Union level oppression, where everyone is too terrified to speak out of resist, and the few that do, just get crushed and sent to the gulag.
Is that your plan? If so, you might want to consider how many people Lenin and Stalin had to kill, to get there.
