“Had you gone to trial, I don’t think there’s any jury that could have acquitted you or would have acquitted you,” Lamberth said, citing clear video evidence of the attack. “You couldn’t have beat this.”

Fairlamb was one of the first to breach the Capitol on Jan. 6, entering through a door that was kicked open shortly after the first wave of rioters entered through a smashed window. He carried a stolen police baton on his way in, though he wasn’t charged with wielding it.

Outside the building, Fairlamb urged other members of the mob forward: “We f----ing disarm them and we storm the Capitol,” he said, an exhortation that was captured on video and played in court. Fairlamb also shouted profanities at officers. Amid the onslaught, he threw a punch that hit a police officer in his face shield.

Three days after the attack, Fairlamb filmed a video celebrating the attack and saying, “They pulled the pin on the grenade, and the blackout is coming. What a time to be a patriot.”
