Also, of course you know firearms more than me.
But also being from the DC area, if I led a mob over just the outside of the white house fence, I would very much expect to get shot. Let alone a 2nd or 3rd door (perhaps last door before the President or Senator). Even on some long distance runs on the weekends if I were to run by the Capitol, I knew if I got too close to the doors (like 100 feet away), a cop would be over to warn me about it within 12 seconds. So to imagine how far Babbit got in her/mob attack into and within the Capitol.... for me, personally, it's not even a question that you'd be taken out eventually.
Nonetheless, the video speaks for itself IMO.
