ICE is normalizing police hiding behind masks. ICE is normalizing violating people's (hard fought and won in the Supreme Court) 1st amendment right to film the police, so that ICE can do their work in secret.
ICE is using biometrics on people who have not broken any law, then saying the federal government will be doing whatever it can in its power to penalize those people now that they have been identified as doing... absolutely nothing illegal but stuff the impedes ICE's ability to operate in secret (among other things a violate of those people's due process rights).
We don't do the whole 'secret police' thing in the USA, and we tend to get angry when the Government violates our Constitutional rights.
The stormtroopers in Star Wars look like they do to be some kind of extreme in anonymous abuse of power. Their squeaky clean white exterior is literally a whitewash of that abuse. That's the one trick that ICE could still pull to complete the transition.
