My concern is more Bannon at the head of the Military. The military is a bunch of serious motherfuckers who have vowed an oath to defend the constitution above all. They also strictly follow the command structure. Which now has them reporting to Bannon, and him to Trump. So they issue a blatantly unconstitutional order to block all immigrants at the border, and the DHS (aka: TSA) holds legal Green Card holders at the airport. THIS is the practical aspect that worries me. Trump says something dipshit loony, and the guys with the guns and no training jump to fulfill his orders without the honor, respect, training, or skills of the military. Nobody at the DHS said, "Ignore that order, because it is stupid and unconstitutional, and has no practical methodology for implementation." THIS is our concern, dude.
