Fuck The USA

They're surely already registering your ID when you enter, so I'm not sure exactly what added surveillance power this gives them? And they're already photographing everyone entering by air, their own citizens included.

Like, the only surveillance benefit I can think of is getting a slightly more up to date photo to track you through flock cameras or something, but given how dogshit the cameras they use at the airports are, I doubt that's the purpose.
