Everything I've read says he was a far right weirdo. It will be interesting to hear his motive, if gives one.And it wouldn’t matter if he was a diehard Commie hating Trump supporter who’d been to every rally he ever held, it wouldn’t have anything to do with me, Trump, conservatives or anything of that kind.
A 4th of July parade is not a commie rich environment.
I believe this is another case of someone mentally unstable and didn't fit in with any group. I think face tattoos scream, "look at me".
