How about you show a proof that a single person was deported without appearing in front of immigration judge as required by law?
The guy you're referring to did appear in front of immigration judge that made a decision he should be deported.
The big controversy was that he convinced a judge that he shouldn't be deported to El Salvador, his home country, because he feared being killed by a rival gang.
He was deported to El Salvador and then brought back because of that.
He will be (already was?) deported to another country because his immigration status didn't change.
Federal judge who put a stop to his deportation was over-ruled by higher court so that particular judge did not, in fact, know the law.
They are trying to bypass any review by being fast and creating facts that prevent US judges from any effective action as once people are outside US jurisdiction they have very little power.
And immigration judges are not actual judges, they are part of the executive.
you’re responding to a comment which states detainees are being sent to concentration camps, places like the deplorably named Alligator Alcatraz. i don’t think we should conflate that as deportation.
Or even when they do end up before someone who knows the law, and that someone says "no, this is illegal, you have to set them free," they say "nah, we can do what we want" and put them on a plane to another country unrelated to the hapless detainee.
