ICE just seems to be a setup for "federal personal thugs".
We've seen them now threatening not just American citizens, other politicians, judges. ICE has been given instructions to simply go operate on their own without direction to "find" people.
The laws surroundings them are surprisingly forgiving / people have few protections. This step seems to just be to dump vast quantities of data they could just for anything they wish from departments that had rules for how they can use that data ... to a group that has few rules ...
