The law is blatantly absent if the executive explicitly states it can detain and deport any person it deems a threat without due process and without duty to notify anyone, let alone a court or judge. It's literally the executive tyranny of a king and absence of balance of power in full action which led to the founding of the United States of America. Even if you're a criminal, last I checked the law, properly enforced, grants you the right to an attorney to prevent exactly this: unchecked executive power.
