We saw how willingly the military went about kidnapping citizens off the streets in unmarked cars, without any identifying badges, at Trump's orders. Helicopters were used, rubber bullets were used, gas was used, on peaceful protesters. I assume that will happen again on a larger scale. No one refused, no one stopped Trump, so he knows he can literally do whatever he wants to do.
I haven't seen anyone stop him from doing anything yet and don't expect it will happen.
