Holding trial for the millions of people Trump wants to deport runs the very real and obvious possibility that not all the judges will rubber-stamp the deportations. In fact, you might start running into judges who deliberately obstruct the process because they have a visceral disgust for the practice of mass deportation.

Can’t have that, because the goal is to ethnically cleanse the country. Once Trump decides deporting people to El Salvadorian death camps is too difficult / expensive, we’re going to start seeing them spring up all over the interior of the country as well.
