You can't refuse to be scanned by ICE's facial recognition app, DHS document say

Per thousands of videos on social media, it doesn’t matter what your rights are anymore, if you try to ask for them ICE will just become even more sadistic and violent, and the DOJ/government will refuse to cooperate in bringing them to justice for denying you your rights- you have no rights or recourse anymore even as a citizen. Moreover, the agents are masked and refuse to self identify as the law requires so you will never be able to say who violated your rights- they are hiding their identities because they are committing crimes. They are not police that follow laws, they are state sponsored white supremacist terrorists.

Fedcops have ALWAYS been like this. They don't go away from an interaction empty handed like local cops sometimes will because the person they're after is following the law.

But of course fed-cops were never seriously prowling neighborhoods where the nearest grocery store is a Whole Foods so nobody on HN cared until now.
