jim360, "People entered the Capitol armed with guns and, apparently, a few pipe bombs and other explosives."
Perhaps I am misunderstanding your quote, but the Capitol was the building demonstrators invaded and I find no mention of guns, bombs or other explosives being found in the Capitol building in those links you provided.
If it was easy to find sources on your gun claim I would not have asked you. Your source of the guns being taken inside the Capitol building would be appreciated, thanks.
