Did the attack on the Capitol involve acts dangerous to human life? Yep. Killed some people, in fact.
Did it violate criminal laws? Yep. A large number of the terrorists have been convicted of such crimes.
Did it appear to be intended to intimidate or coerce a civilian population and influence the policy of the government by intimidation or coercion? Yep. Trump told them to do that. Many of the insurrectionists admitted the fact.
Was it intended to affect the conduct of the government by destruction, assassination or kidnapping? Yep. Even had a gallows built to hang the vice president.
Did it occur within the territorial jurisdiction of the United States? Yep.
Feel free to show that they didn't do all those things caught on video. What do you have?
Specifically, U.S. Code at 18 U.S.C. 2331(5); that's the law.
I'd be tempted to bail out, too, if I had all that to explain away. As you now realize, the relevant law nicely describes what the insurrectionists were doing.
But yes, this thread isn't about the domestic terrorists who attacked the U.S. Capitol. It's about a single person who was also breaking the law, and apparently tried to harm an officer trying to do his job. If he was actually grabbing for the officer's taser, then it's not surprising or criminal that he was shot. Same goes for the terrorists. Police seem to have been remarkably restrained, only shooting one of them.
The justice system is dealing with the rest. FBI is still poring through social media to identify more of them.
