OK. I would note again the video cited by the OP of this thread. Also, the OP of this thread.
From the video I’ve seen, there was an enormous amount of noise and commotion from people shouting all sorts of things, and I highly doubt if everyone would hear glass breaking especially over a large area. Perhaps more importantly, I don’t think the crowd arrived at nearly the same time, and many people arrived after the capitol had already been breached, at which time the police had retreated and the doors were open and people could peacefully enter.
