Because they were close to the Congress people. Because one broke through. The mob stopped. Had they broke through, more would have been shot.
It's a simple self defense. What would YOU do if someone gets in your window? Would you be called a coward if you shot the person?
Bullshit. The congress critters were led to safety long before that single shot was fired, as were many of the mob inside already.
I'd be in prison if I shot an unarmed intruder coming through my window.
