A former Canadian Armed Forces reservist plotted with other members of a white supremacist group to carry out “essentially a paramilitary strike” at a Virginia gun rights rally, a federal prosecutor said Wednesday. U.S. Magistrate Judge Timothy Sullivan agreed to keep Patrik Mathews, 27, detained in federal custody pending a Jan. 30 preliminary hearing. Mathews leaned back in his chair and quietly laughed when the magistrate read aloud a transcript of a video in which the Canadian national advocated for killing people, poisoning water supplies and derailing trains. “This is a very dangerous person,” the magistrate said during Mathews’ detention hearing in Maryland. “He espouses very dangerous beliefs.” Mathews and two other men were arrested last Thursday on federal felony charges in Maryland and Delaware, just days before they were believed to be headed to a pro-gun rally in Virginia’s capital. Federal prosecutors said in a court filing Tuesday that a hidden camera captured the men discussing “the planning of violence” at the rally and expressed hope that bloodshed could start a civil war. Monday’s event had attracted tens of thousands of people and ended peacefully. “This is a domestic terrorist investigation,” Assistant U.S. Attorney Thomas Windom said Wednesday. Defence attorney Joseph Balter said Mathews may have used “alarming” and “outrageous” language in conversations captured on video at a Delaware home in the days leading up to the rally. But Balter said his client’s statements are protected by the First Amendment as free speech and did not reflect any specific plans for violence.
