Anti-ICE gunman Joshua Jahn had ‘hatred’ for government – whose attack was ‘very definition of terrorism,’ feds say | 25 Sept 2025 | Dallas anti-ICE gunman Joshua Jahn harbored deep resentment for both immigration authorities and the federal government, and set out to inflict maximum casualties in an attack officials called “the very definition of terrorism.” Speaking at a press conference Thursday morning, Acting U.S. Attorney Nancy Larson said hand-written notes found at Jahn’s residence by the FBI referred to the work done by ICE agents as “human trafficking,” and said the Dallas facility he riddled with bullets was nothing but “people showing up to collect a dirty paycheck.” The gun used by Jahn, who authorities believe acted alone, was an “8MM bolt-action rifle” he legally acquired in August, FBI special agent in charge of the Dallas Field Office Joe Rothrock told reporters.
