Here's the Cambridge definition.
an organized attempt by a group of people to defeat their government and take control of their country, usually by violence
Key phrase here is "take control of their country". I don't see how that even applies here. There was literally no avenue or path for them to do so.
They tried to stop the certification of the vote.....they then left. Capital police let them walk the F out with no arrests. I'd think folks set on insurrection would have stuck around....maybe bring some fire arms with them?
Just not seeing the "insurrection"....
What they did by breaking in, attacking capital police and holding up certification was bad enough and they have to be held to account and arrests have been made.
