Because your post from the beginning was dumb. You saying were the locks engaged? Yes, that's why the mob outside couldn't open them! But you think that one guy can push the doors and they magically open. You believe an entire mob can't open the doors but some chubby guy who maybe weighs 230 lbs can just throw his shoulder into it and it magically opens. The mob wouldn't be able to get those doors open even if they drove a truck up to them, attached a chain to the door handles and floored it. Those handles would come off before the doors would open.

But you believe some chubby guy is apparently superman, all cops and security in DC(who spent trumps entire term shitting on him and telling lies) are Trumpers and that Congress can't overrule him and call in the national guard. You also believe that the security for the entire government is that dumb and never planned for anything like that to happen...especially when you consider in 1983 far left Jewish terrorists actually bombed the Capitol. Probably no coincidence that the head of that terrorist cell was Susan Rosenberg who on his last day as president was pardoned by Bill Clinton. She later when on to help handle the finances for black lives matter aka another far left terrorist group.
