White supremacists violently stormed the capitol with no regard for law and order.

Let's not pretend that disregard for law and order is limited to Trump types. Besides, the January 6th protests were mostly peaceful.

Umbrella Man has been linked to Hate groups

Since I'd never heard this claim before, I'll save everyone else the bother of looking into it. "Umbrella Man" is the guy wearing a gas mask in this video. Minneapolis police made no headway identifying him for months until receiving an email tip saying that the Umbrella Man was one Mitchell Carson, who is basically a stereotypical skinhead type. Minneapolis Police requested a search warrant for that man's cell phone activity at the time of the window-smashing, which officials say/imply led to the Glorious Floyd Demonstrations becoming violent. This Mitchell Carson was, according to Minneapolis police, connected with a Hell's Angels biker gang and the Aryan Cowboys prison/biker gang.

There's a lot of loose language in the media reports about the investigation that (intentionally?) gives the impression that the police made a positive identification, proving that Umbrella Man = Mitchell Carson. In reality, the police were following up on a lead that appears not to have panned out. Carson was not charged at the time (late July last year) and apparently still has not been [1][2][3], so it is extremely implausible that he was Umbrella Man. The bottom line is that it is incorrect to say that Umbrella Man has been linked to hate groups because (still) no one officially knows who Umbrella Man was.
