They don’t need to murder you. The criminal cases against ICE protesters in Texas hinge on the government’s assertion that carrying a weapon to a protest is evidence that you are planning a terrorist act (also, wearing black, using Faraday bags for your phone, and traveling to protests in groups are all now considered evidence that you are planning terrorism). So, carry a gun near ICE and they will call you a terrorist and disappear you.
Murder is bad optics, but label someone a terrorist and America will cheer while they execute you.
