Hey, asshole--the purpose of the Capitol breach wasn't to vandalize property. If they were just trying to cart off the Speaker's podium or trash her office, maybe I'd agree with you. But they weren't doing that.
Their purpose in entering the Capitol was to carry out a putsch. Don't take my word for it--take that of Elizabeth from Knoxville or any number of other assholes who are on social media.
They wouldn't have stormed the Capitol if it were empty, as the protesters tried to do with the courthouse in Portland. They stormed the Capitol precisely because it was full with both houses of Congress sitting in joint session and being presided over by the Vice President. Their goal was to prevent that joint session of Congress from counting the electoral votes, which they accomplished, even if it was just for a few hours?
Why? What is accomplished if they prevent the electoral votes from being counted?
They honestly thought--because the were basically told this by Donald Trump and any number of his acolytes--that if they could prevent the electoral votes from being counted, then the person who was elected president in a free and fair election conducted according to constitutional processes would be prevented from taking office. That would allow Trump to remain in office, even though he lost the election. Presumably, he would remain in office indefinitely. That's definitely what Trump has offered in the past.
So let's get that real fucking straight. Their crime wasn't vandalism. Their crime wasn't theft. Their crime was attempting to overthrow the government of the United States. And yeah--putschists get shot.
