The Department of Homeland Security released images of firearms confiscated from anti-ICE "rioters" in Chicago on Sunday. DHS says it has launched an investigation after discovering "what appears to be" an explosive device outside the Chicago ICE facility. "11 violent rioters were arrested last night in Chicago outside the ICE detention facility: These are two guns that were taken off rioters in Chicago right against the fence at our ICE detention facility," DHS wrote. "An investigation is underway into what appears to be some sort of explosive device found last night near the ICE Chicago detention facility," the statement continued. The confrontation came just two days after a shooter opened fire at an ICE facility in Dallas, Texas.
