Yes, it genuinely is looking more and more like a full-scale conspiracy to take over the government. Did you see the footage of the black policeman who lured the rioters away from the doors of the senate chamber and upstairs where they were met with more police? If you're right about the bloodbath that was planned in the senate, that man probably saved democracy in the USA.
It seems very like the plans laid by the Catholic terrorists for the Gunpowder Plot in 1605 - decapitate the country of its leadership by detonating the gunpowder under the Parliament, and then fill the vacuum.
I'd be interested to know where Ted Cruz and Josh Hawley were at that precise moment too.
I too hate conspiracy theories. Long study of history tells me that big events are more often caused by a cock-up than a plot - but not always.
