So honestly, this guy is a funny story, and there is no way I can really do it justice here, but I will give you the overview anyhow.
He is a true believer in every sense of the word and lives in a vaguely attached reality. Probably two or three times a year he will call me in a panic over some totally wacky conspiracy theory he has heard from god knows where. I think the last one was France, India and maybe Turkey were going through with their alternative currency and the USD was going to be eradicated in 3 months. This was maybe in the spring of this year? Anyways. He was a nuclear engineer in the Navy, so clearly has intelligence, but whatever that thing that keeps you in touch with reality is not firing on all cylinders.
As far as the riot, he was there for the rally up the street (I actually talked to him on the phone while that was happening. He was like "hold on a second, the President is speaking", which is when it dawned on me where he was). He got sucked up into that through naiveté, and didn't actually raid the Capitol. And on the plus side my guys gave him a hilarious amount of shit for it.
So this isn't a guy who is consciously lashing out and knows he is hurting people, he is a true believer.
