Christ. I have a very depressing outlook on this and want to elaborate once I get off work. In short - there's a very strong impulse in middle America that institutions of law and order have fundamentally decayed in major American cities - that rioters are tearing up the place and are facing virtually no legal consequences - or very minor ones at best.
The amount of support for that Kyle Rittenhouse kid boggles the imagination of anyone who lives outside the U.S. Bringing a gun to protect a store and getting into a confrontation like that that leads to you shooting people is insane. You'd be doing life in prison anywhere else but I wouldn't be surprised if he's acquitted. Remember when George fucking Zimmerman was acquitted? In these people's minds if you genuinely believe (incorrectly) that the police are not protecting civil society and the rule of law you have to do it yourself.
A lot of Americans are clutching their palms hoping that Trump comes in to restore "order." It's like my dad said, are any of these people employed? During a TV broadcast of a riot in broad daylight during the week. That's how a good chunk of the population looks at the "other."
Or any time someone gets shot by police, people immediately bring up their criminal history. Even the guys that got killed by that kid. Painting other humans as moral degenerates is the easiest, most self-satisfying thing you can do. Everyone is some level of fucked up. Thinking is hard.
I don't trust the polls. People who vote Trump don't get polled. Either they don't pick up the phone or lie. And everyone gets antsy as election day approaches.
