Why wouldn't they follow through?
Think about how much "due process" was required to let several million people enter the US illegally during the past administration. Consider how much effort is being expended right now to ensure due process for one person. (This isn't about the merits of the case.) Ponder how many people would like to see illegals - particularly violent, or even allegedly violent illegals - sent away with approximately the same ease as they were let in. Do you really think those people would let up? I suppose that the people who want to see achievements of the previous administration undone are going to be as energetic as the people who want to see those achievements preserved. What I am observing: in politics, the response to "not one step back" is "scorched earth". Immoderation is met with immoderation.
I’m gonna segue off something here; I recognize this wasn’t the main thrust of your reply, but it’s critically important.
Due process stops being due process if it’s very existence and application becomes conditional. Different processes are built to address different sets of facts. Due process for a criminal conviction is distinct from due process for deportation on the grounds of misrepresentation, and both of those are distinct from due process for an administrative challenge to loss of a federal job or security clearance. The point is that, whatever due process exists for a particular set of circumstances, that due process
must be afforded. It’s the
existence and application of due process itself that is the vital ground. Once the administration starts to get away with circumventing or outright ignoring due process in one sphere, it becomes easier in others. Mere days after the first batch of people were shipped to El Salvador under a farcical application of the Alien Enemies Act, we have the White House secretary admitting they’re looking at the legality of doing citizens too.
The fight for due process matters because even if you aren’t vulnerable today, you could be vulnerable in a month or a year. We’re already seeing pretextual police stops of Latinos who are born and raised US citizens. We’re already seeing at least one U.S. citizen arbitrarily detained by ICE and held in custody for
ten days on purported ‘immigration’ grounds before release- are citizens to carry their papers now, to be surrendered for inspection on demand by curious government agents? Lawful residents on student visas are having their visas revoked and are being kicked out of the country for minor dissents against the current administration which are completely covered by the first amendment.
Stripping due process is contingent upon people accepting the abuse in the case of unsympathetic edge cases. It starts with the easiest, least sympathetic ‘other’, and quickly grows into more people being falsely lumped within that category. Once it becomes normalized at that level, then there’s a next step.
A state that holds due process in contempt is a state that will arbitrarily to anything from throwing a dissident in jail for no crime to illegally firing a federal reserve chairman based on a policy disagreement. Due process is simply the mechanics that have evolved to administer the overlapping and conflicting powers of the three coequal branches of government. Once the executive makes it normal to usurp that you have an autocracy.
To put it most bluntly: in a country that abandons due process, people like you lose most of your protections against people like me. Once that protection is gone, and ‘people like me’ has had a couple years to have the chain of command filtered by the executive for political purity, how does that play out if you’re at all vocal against the regime?
So yeah, due process for some guy who snuck into the country and might have abused his wife matters. When the camel starts to stick its nose under the tent flap sometime you have to kick it in the snout. This much effort is being expended for - at the moment - one person, because at this level it can still be fought and won hopefully without violence.
