That was just a protest that members of the FBI whipped into a riot. They didn't actually insurrect (well, maybe a tiny core did, I dunno) because while people were highly suspicious that some cheating happened, nobody could be sure.

But what is happening now with blatently anti-democratic and blatently illegal (but may succeed despite that) attempts to get Trump taken off the ballot... people will be far more sure of what is happening, and so far more people will be driven to action with a righteous kind of anger, without the hesitation of not being sure if the vote was stolen or not.

That's my thinking anyways.
