In the immediate aftermath of January 6, 2021, investigators observed a phenomenon: police officers who responded to the day's violence at the Capitol could not always remember the assaults they suffered at the hands of a pro-Trump mob. But as he reviewed hours of body-worn camera footage, Metropolitan Police Detective Jonathan Lauderdale could see everything — the shouts, the shoves, the punches, the profanity. "Reviewing that over and over again was traumatic," Lauderdale said Tuesday, recalling the "complete chaos" of January 6, 2021, at the latest jury trial connected to the Capitol siege.
