Basically, combined with the huge budget being dedicated to hiring new Gestapo to staff the ICE legion of masked thugs, absolutely anyone can be desaperecido on a whim, with virtually no recourse. Not just by order from Trumpolini or by mistake, but by any ICE agent with a grudge or desire to get rid of somebody. Say he has the hots for your wife. He and his team can drop in at your job, whisk you to the airport and before the day is out you're standing on the side of the road in cartel country in Mexico or a war zone in Sudan.
Drop a comment on Instagram criticizing Israel or a joke about his his mental acuity goes viral, 12 hours later you're in Nigeria with no passport and an empty wallet.
Trump makes Stalin and ICE makes the KGB look like amateurs.
