What are you snorting? While the rioters didn't directly kill anyone with their guns, they did use them in a threatening manner, which contributed to the chaos and violence of the attack.
Some rioters openly carried rifles and handguns, displaying them in an intimidating manner and causing fear among the Capitol Police and members of Congress. Several rioters who were later arrested were found to be carrying concealed weapons, including handguns and zip ties, which led to fears that they were planning to take hostages or engage in violence.
