Remember in Batman where Batman went and grabbed a guy and dropped him in front of the courts? We need that, except instead of Batman we just need someone to ask El Salvador to release this guy, then bring him back to the us, and do what the trump administration will not do.
After all, Trumps team says it's in error and the guy has done nothing wrong. Surely if he shows back up at customs he'll be let into the country to get to his day in court, right?
