The simplest explanation is they're trying to make sure Trump can't run again. Things are so weird that I think there's a chance that another POTUS election could be held in the next year or two for some unprecedented reason.
Problem with screenshots is it says the relative time, could be weeks ago, and it could be fake altogether. Archive twitter link somehow would be ideal. Until then, twitter sucks, but if you're going to reference a tweet, link or it didn't happen.
People drive themselves insane by not being able to honestly acknowledge conflicting points that can both be true. Was it a good thing that citizens made their presence known and freaked out congress? Yeah, in a way. Did anything good happen? No, everything that happened that day was bad, from the corrupt Congressional session on. Should people do it again? Yeah, maybe. In hindsight it's always a bad idea, but in the moment there are only bad ideas to choose from.
Trump's communication was abhorrent. Nobody knew what they were supposed to do there or for how long, but Trump made it seem really important that they put pressure on congress or something, and then congress started certifying the nonsense and freaked them out. It probably only took a word of encouragement to get them to storm in. Not a lot of rational thinking, because nothing about it was clear to begin with.
There's little need for physical concentration camps anymore to control people. People can be imprisoned electronically.
