Excellent point.
One way that the Statists could eliminate resistance is with a false-flag operation (or an allowed incident) to justify locking down some area [maybe a county or a city] to include controlling comms. In such a situation, it would be easy to make particular people disappear. The horrendous beauty of this sort of plan is that only a very small core of people need to know/instigate/execute the true objectives of the mission.
Tom Clancy did something similar with Clear and Present Danger where a weapons-testing exercise was used to support/hide what was essentially assassination via 500lb bomb air-dropped but made to look like a car-bomb.
They know there’s isis on the border. All they have to do is tell them is to lock the area down. then Barrys crew can come in and do whatever they like.
Military need no no more than establish initial control then leave. And never once receive illegal orders to question.
