At 1:13 p.m. on Jan. 6, a D.C. police commander facing a swelling crowd of protesters on the west side of the U.S. Capitol made an urgent call for more officers in riot gear. “Hard gear at the Capitol! Hard gear at the Capitol!” Cmdr. Robert Glover shouted into his radio. By the time they arrived, the Capitol grounds were already being overrun by a mob intent on overturning President Donald Trump’s electoral defeat.
