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 ...
You put that between parentheses as if it was just a detail, but it is the fundamental question that nobody is talking about: what happens after their guy is gone?
Are they really ok with president AOC getting all of Trump’s powers? Or do they secretly hope democracy in the U.S. comes to a halt?
An argument can be made after things like the second Iraq war that we have already entered the decadent empire phase of US history and the President effectively does have a great deal of dictatorial power. It's not supposed to be possible to wage a war like that without a congressional declaration, making such wars a pretty huge abdication of power by the legislative branch. If the President can just start a war on a whim, that power can be used to drag along the entire rest of the government.
Now, with ICE, we are establishing a lawless executive branch police force. This is just the unilateral power of the President to wage war coming home and being applied to domestic affairs. It will soon be possible, if it isn't already, for the President to order their own independent police to do anything, and if it is considered illegal the power of the pardon can be used to make that go away. The arbitrary power of the pardon is a pretty awesome power when you think about it.
When the ratchet gets far enough down this path we may indeed see a president remain in power forever like Xi Xinpeng. Trump may or may not be that person. If it's not him it might be the next, or the next. It could just as easily be a left-wing populist demagogue as a right-wing one depending on which way the winds happen to be blowing when the final ratchet click happens.
Rome continued to exist for quite some time after its Republic collapsed, but it was definitely the beginning of the end.
