Overview

• Investigators say casings labeled "ANTI-ICE" were recovered after a shooting at a Dallas ICE facility that left two detainees dead and the suspected gunman later deceased.
• People briefed on the probe identified the Dallas suspect as 29-year-old Joshua Jahn, as authorities continue to examine motive and what the markings signify.
• The inscriptions echo recent cases, including bullets marked "Deny Delay Depose" in the 2024 killing of UnitedHealthcare’s Brian Thompson and meme-laden casings tied to Charlie Kirk’s assassination in Utah.
• Scholars and former investigators say such markings function as performative mini-manifestos that can be ideological or meme-driven, often cryptic and difficult to interpret.
• Political figures have cited the Dallas casings to claim ideological motives while others urge caution, and experts warn the publicity risks copycat behavior and potential red herrings for investigators.
