That's a ridiculous ask. You and I don't get to have our own version of what due process is - it's part of the US Constitution and only the courts (especially the Supreme Court) are entitled to interpret it. SCOTUS has already done so, and I already posted their ruling of what due process means for the people facing deportation proceedings.
I don't have any personal experience of how deportation proceedings should work but again, I think the Supreme Court justices do, which is why I would defer once more to their obviously superior expertise.
Nor have I expressed any concern or outrage about this or any other deportation proceedings, my only concern is to challenge your understanding of due process which you seem to think includes being detained in an ICE facility, when the Supreme Court ruling would indicate that it doesn't.
You're the one who claimed that them being detained was part of due process so it's actually incumbent on you to provide evidence that backs up that claim.
Accordingly, please provide evidence from a reputable source (a legal site or court ruling should suffice) that being detained forms part of a person's due process rights.
