So look,v this is just gonna happen. It’s legal to film people in public (in the US) and we all know stores, etc. are already using facial recognition.

The real problem here is the (apparent, though almost certainly assured) lack of responsible use of the data. Scanning faces means you also get time, place, and event/activity, and that citizens then have zero control of what the govt does with this, who they share it with (e.g. Palantir), etc. All prior collection of US person data required appropriate approval, limited scope of access, and timely adjudication/disposal. But ICE is (again, apparently) operating outside the law.
