From the Statement, “Officials examined video footage posted on social media, statements from the officer involved and other officers and witnesses to the events, physical evidence from the scene of the shooting, and the results of an autopsy.  Based on that investigation, officials determined that there is insufficient evidence to support a criminal prosecution.”

 The DOJ continued, “The investigation further determined that Ms. Babbitt was among a mob of people that entered the Capitol building and gained access to a hallway outside “Speaker’s Lobby,” which leads to the Chamber of the U.S. House of Representatives.  At the time, the USCP was evacuating Members from the Chamber, which the mob was trying to enter from multiple doorways.  USCP officers used furniture to barricade a set of glass doors separating the hallway and Speaker’s Lobby to try and stop the mob from entering the Speaker’s Lobby and the Chamber, and three officers positioned themselves between the doors and the mob.  Members of the mob attempted to break through the doors by striking them and breaking the glass with their hands, flagpoles, helmets, and other objects.  Eventually, the three USCP officers positioned outside the doors were forced to evacuate.  As members of the mob continued to strike the glass doors, Ms. Babbitt attempted to climb through one of the doors where glass was broken out.  An officer inside the Speaker’s Lobby fired one round from his service pistol, striking Ms. Babbitt in the left shoulder, causing her to fall back from the doorway and onto the floor.”

More from DOJ,  “Specifically, the investigation revealed no evidence to establish that, at the time the officer fired a single shot at Ms. Babbitt, the officer did not reasonably believe that it was necessary to do so in self-defense or in defense of the Members of Congress and others evacuating the House Chamber.”

It is unclear how the investigation determined the officer or others were in imminent danger of death or serious injury, the standard in this country to use deadly force. The officer has never been identified.
