The cases against Biggs and Nordean turn what had been the Proud Boys’ greatest weapon – social media – against them as authorities have detailed their alleged misdeeds using material that they and others posted online.

For example, a grand jury indictment of a Texan, Nicholas Decarlo, and the founder of the group’s Hawaiian chapter, Nicholas Ochs, alleges that they together inscribed “Murder the media” on the front door of the Capitol before stealing a Capitol police officer’s handcuffs. In an affidavit, an FBI special agent says that they determined that Ochs had been in the building from his own Twitter account.

Meanwhile, Dominic Pezzola and William Pepe allegedly conspired with each other in a sequence of events which included Pezzola assaulting a Capitol police officer, stealing his riot shield, and then using it to smash in one of the Capitol’s windows. The evidence cited in affidavits includes Pezzola’s account on the shuttered conservative-friendly social media service, Parler, and videos posted online by other rioters.
