Well, people already tried to wipe out The Pentagon on 9/11 so I guess your suggestion to do that is out. People are already peacefully protesting all over the country, so no issues there. The riots are such a small part of what's happening.
You've already got Trump gassing people out of Lafayette Park so he can do a photo op with a Bible in front of Church. The violence is already being perpetrated by the police and the government. He's bringing the violence TO people. I think some shattered glass in storefronts and some looted shoes are the absolute least of the issues we are seeing during all of this.
I get that you think if people aren't perfectly well behaved and falling in line that somehow there are already going to be dire consequences, but people are already living through some pretty terrible things.
Like I said, people have to start somewhere. You can't control for the individuals that show up in their black hoodies and backpacks throwing molotov cocktails because they get off on it. Those are the people you should be appealing to if the riots are your concern. Or maybe the police that are abusing their power. Up to you which is the problem that needs to be addressed first.
