I don't think you have the facts of the matter or the context right here. The government absolutely does not have the right to expel legal permanent residents without due process. And 'keeping their mouths shut' and pretending otherwise is not even remotely, feasibly "reasonable". The Supreme Court literally just ruled that residents with much less legal status than this person must be given due process -- an entirely obvious statement. But one which apparently needs to be reaffirmed by the highest court in the land because of how casually this administration seems to discard basic tenets of U.S. law. So you're just outright wrong.

The government absolutely did prevent this person from 'saying whatever he wants' -- he was essentially abducted from New Jersey and sent to detention in Louisiana without the ability to contact his family or his lawyer, or get any sort of hearing. It's only after the fact, due to the work of his lawyers and the public outcry, that he was able to submit a habeas petition. You seem to be downplaying how violent and seemingly corrupt the government's actions were in this case (I guess because you ultimately disagree with whatever you imagine this person did). Just because one Louisiana DoJ immigration judge sided with their own branch of government doesn't really lend plausibility to the government's case.
