I'll concede that I couldn't find an article that gave the status of the cop after the attack. If he was the same officer that later died, I can't find an article that makes that connection. But the issue at question was whether it was an armed insurrection. Do you still maintain that it was not an armed insurrection because there were no guns? The better question, I think, is whether you think it was an attempted insurrection at all? Do you think they showed up on the steps of the Capitol because they were just mad or do you think they showed up to stop Pence and Congress from certifying results?
I posted this earlier but maybe it got lost.

The Capitol Policeman, Brian Sicknick, died of natural causes according to the Medical Examiner.
As to "armed insurrection", there was the shaman dude with a flag on a spear...and...what others? Now, Shay's Rebellion...THAT was an armed insurrection.
I'm going to guess 99.99% showed up at the Capitol because they were mad...with maybe a small number of dumbshits that wanted to (and actually thought they could) stop them from certifying results.
