from members of Congress trying to hide themselves from the rioters. Lt. Byrd was their last line of protection...he had his gun raised for several minutes in full view while yelling for the mob to stay back. If he were to let Ashli Babbitt through, everyone would follow her...Absolutely Justified for him to shoot...and it did indeed stop the mob.
The truth of the matter is that Donald Trump is responsible for her death...he Lied about a 'Stolen Election' and instigated the attack on the Capitol which led to her shooting.
