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.
If the people carry something and change their minds and moods, have fun holding back that energy with a creaking dam made of paper. Even this Ice nightmare, was voted in democratic and will be one day, when the mood has swung again, pushed back by the people in some colorful revolution.
