A little bit of yellow and a little bit of light blue. Nice.
Can't dismiss this mob activity as simple trespassing/vandalism. This was, at the very least, a "riot." Preparation. Breaking and entry. Over a hundred police officers injured. Some died, and we're lucky there wasn't even more death.
Now, was this riot an "insurrection"? In other words: not just a riot with a political bent, but with an aim of affecting the course of U.S. history?
Here are the factors to look at:
(1) The date of the rally (Jan. 6, 2021, when Congress was due to certify the transition of power);
(2) The location of the rally (Trump could have held it anywhere in America, but he chose Washington, D.C.), and;
(3) The expressed intentions of the rally participants.
Giuliani warmed up the crowd with words about "trial by combat." In his own speech, Donald Trump himself used just enough plausibly-deniable language to cover his own ass. He did not actively tell them to go try to overthrow the government. He did not tell them to go maim and kill. He in fact urged his followers to be "peaceful," though apparently not loudly and repeatedly enough. What he did say is that his followers should go and give the Republicans "courage," and sent them marching down Pennsylvania Ave. in the direction of the Capitol.
His speech has been likened to a mafia boss saying to his capos, "who will rid me of this problem?"
It should be noted that many of Trump's followers were less circumspect than Trump himself, expressing their wishes to actually keep Trump in power, not to mention hunt down certain government officials: "Hang Mike Pence," "Where are you, Nancy?" etc.
Anyway. After all the carnage that day, the effort amounted to nothing, of course. It was kind of silly to expect that this temper tantrum would have changed anything. Congress and the Vice-President had no constitutional authority to reject the decision of the voters, and of the Electoral College, no matter what Trump said.
So: Reasonable minds can differ on whether this was a bona fide attempt by Trump to stay in power, or just a way to enact violent revenge and retaliation on Congress.
But any way you slice it, this was the Executive Branch organizing a mob of loyalists to attack the Legislative Branch (and another member of the Executive Branch: The Vice-President) on a key day for the transition of power. No question.
Nothing like this has ever happened before in American history. It was a Big Deal.
