Online Talk About ‘Civil War’ Could Inspire Real-World Violence, DHS Warns Cops

DHS also cautioned that it is unable to get a grasp on the full scale of the threat. “We lack a complete threat picture due the ability of some DVEs to evade law enforcement using advanced encryption,” the agency wrote. And because extremists have gotten tech-savvier, intelligence officials don’t really know whether they’re joining forces.

This is a trend that researchers and experts have observed especially since the Capitol riot nearly four years ago. “We’ve seen people move from mainstream platforms, where they were active in organizing January 6, and shift to platforms that offer more perceived anonymity, less moderation, and less reporting to law enforcement,” said Katherine Keneally, US director of threat analysis and prevention at the Institute for Strategic Dialogue. “It is a law enforcement intelligence gap, it’s a gap for the whole field. We don’t see everything we once did.”

Regardless of whether extremists are coalescing or whether the threat remains atomized, the assessment recognizes that online chatter about civil war had already inspired plans for real-world violence.

In January, Justin Mohn, a 32-year-old man from Levittown, Pennsylvania, beheaded his father, a federal employee, and displayed the severed head in a 15-minute tirade uploaded online. In the video, titled “Mohn’s Militia-Call to Arms for American Patriots,” Mohn urged viewers to rise up against the government and hunt down federal agents and judges.

Months later, in March, federal agents arrested Benjamin Brown, a 45-year-old man in Waterville, Maine, for making threats to kill President Biden and other officials. The man allegedly claimed he was stockpiling weapons and ammo for a civil war and, according to an affidavit, said he wanted to hunt migrants and “burn Washington to the fucking ground.” Brown was charged with making interstate threats.

Then, in May, a stop for a minor traffic violation in Pekin, Illinois, led police to discover a padlocked canvas bag inside the vehicle containing a .45-caliber pistol and two homemade pipe bombs belonging to 34-year-old Dalton Mattus. When investigators searched Mattus’ home, after a brief standoff, they allegedly found more pipe bombs. A local radio station reported that Mattus told police he hoped to use the bombs defensively against “undocumented immigrants and a corrupt government.” It turned out that Mattus also had an extensive social media presence; for years, he had promoted QAnon conspiracy theories and civil war fantasies, advocated violence against federal officials, Democrats, and immigrants, and urged his followers to prepare for imminent conflict.
