Attorneys: Members of white supremacist group pose significant risk to community, world

Federal attorneys are asking to detain Boise resident Matthew Allison, an alleged leader of a transnational white supremacist group, pending his trial.

Allison, 37, was arrested Friday along with California resident Dallas Humber, who together are said to lead a group called Terrorgram Collective, which promotes mass violence and the idea of “white supremacist acceleration.”

Allison and Humber are charged with 15 counts of soliciting hate crimes, soliciting the murder of federal officials and conspiring to provide material support to terrorists, all felonies; Allison appeared in federal district court in Boise on Tuesday and did not enter a plea.

After his arrest, Allison confessed in a recorded interview with authorities to engaging in the acts he is charged with, according to court documents filed Tuesday.

Assistant U.S. Attorney Angela Scott filed a motion Tuesday to detain Allison and Humber, arguing the two pose a “grave danger to law enforcement officers, people they believe to be government informants” and “members of the worldwide community.” Federal attorneys also contend the two are a significant flight risk.

The hearing on this motion to detain is slated for Sept. 18, according to KTVB.

“The Defendants are self-proclaimed and unapologetic white supremacist terrorists who have solicited like-minded extremists to commit bias-motivated mass murder, political assassinations, and terrorist attacks on critical infrastructure,” the motion said. “The defendants proudly support terrorism and violence, and they have dedicated their lives to inspiring people to commit terrorist acts.”

Allison has told other members of the Terrorgram Collective that if federal agents try to arrest them they should “go down (expletive) shooting,” according to court documents.

When the Boise man was arrested, he was wearing a backpack containing zip ties, duct tape, a gun, ammunition, a knife, lock-picking equipment, two phones and a thumb drive, the motion said. Federal authorities also found in his apartment an assault rifle, ammunition, a “go-bag” with $1,500 in cash, a passport, birth certificate, clothes, deodorant, bags of pills, a firearm holster, a black balaclava and a mask from the neo-Nazi terroristic group Atomwaffen Division.

In the motion, the attorneys argue that both defendants pose a significant flight risk because of the “minimal connection” to their communities. Both are unmarried, have no children, work unsalaried jobs and do not own homes, the motion said. Humber recently expressed her intent to move to Idaho from California, according to the motion.

“In short: there are no forces tethering them to their communities strong enough to countervail their incentive to flee the jurisdiction to avoid life in prison,” the document said.

The indictment, which was unsealed Monday, alleges the two have provided detailed instructions to Terrorgram members for creating explosives, printing guns, and carrying out mass shootings and other acts of violence based on race, religion, sexuality, and gender identity. There were three attacks that the group inspired that were carried out or nearly carried out provided as examples in the court document.

If convicted, Allison and Humber each face a maximum cumulative sentence of 220 years in prison.
