These “BLM riots” continued for 6 months (longer, actually — up to a year or more) if you watched FOX News. If you actually live in one of the cities that supposedly burned down, as I do, they were over in a couple weekends.
That said, these things can happen when the police murder people without justification! It’s kind of in our American DNA!
(See, e.g. Boston massacre, Boston Tea Party)
But what is entirely new in American history is a defeated Presidential candidate rallying his own supporters to try to effectuate a coup, ending the peaceful transfer of power in our independent history as a nation. That is brand new, as of Jan. 6, 2021.
And as you point out, in some cases, the Capitol Police were caught off-guard. No one expected white people to get this rowdy!
But in one other case, the Capitol Police decided to play Good Guy With a Gun and sent one of these MAGA traitors straight to the pits of hell. See, e.g. Ashli Babbitt. And actually, she’s the only traitor who was shot, which is remarkable under the circumstances.
F**k around again and find out!
