Most of these departments have rules about how they use our data. ICE now gobbles it all up and can use it without rules by a department that operates with little regard and lots of exceptions to typical protections for citizens afforded by the constitution.
The majority in SCOTUS does not seem to care (it’s ok as long as their guy does it). Whatever rules we thought there were seem to be out the window because someone magically moved data or ICE got to do it or so on ...
Almost the entire US constitution applies to non-citizens in the country, with some small exceptions like voting and holding public office.
This is sort of a classic example of a slippery slope, FWIW. As soon as you deny anybody due process, the category of people that applies to will just constantly expand.
Now, there's basically nothing stopping immigration officials from immediately deporting anybody they want, citizen, non-citizen, illegal or legal immigrant.
What nonsense. We have the courts. There must be a valid determination made that a person entered illegally for expedited deportation to apply. Due process applies to that determination - if it is not made correctly then sue. But more importantly why on earth would it not be made correctly? If you can’t prove that you’re a US citizen then something is very wrong.
