The FBI arrested a Texas man on Friday who allegedly hurled a lit firecracker at police officers during the Jan. 6 Capitol riot. David Judd, 35, has been charged with assaulting police, resisting or impeding officers, and civil disorder for what prosecutors describe as his attack against police guarding the Capitol building’s Lower West Terrace doors. Judd was taken into custody by the Dallas FBI field office on Friday morning. According to an affidavit, he was caught on surveillance footage joining other protesters in trying to shove their way through a line of police officers. He then allegedly helped other protesters use riot shields stolen from police to make a “shield wall” against officers before lighting a firecracker and throwing it at the line of officers.

A fellow member of the crowd was apparently so shocked by the move that they yelled: “You going to do that and run away! What the fuck.” According to the affidavit, that same unidentified person then notified others in the area that “he threw a firecracker, a big giant, what the…” In addition to being captured in footage from the riots, Judd also posted to social media before the rally boasting of having “a license to carry a firearm” before proclaiming it was time to “fight to save this country and support the greatest president,” federal prosecutors say.
