Do they partner with Clearview or Flock or anyone else? "Collect" seems like a weasel word that still leaves lots of options on the table.

Palantir isn't collecting it, they are storing it and processing it after it has been collected by ICE.

Their defacto scan everyone isn't to determine citizenship, it is to collect the data in the first place. They want to get as much data into their system as possible.

Dumb question, but can't they get around that considering they are looking for people whom are not US citizens?

that's a boldface fuckin lie
