"They do not contest deportation because this would mean they get fingerprinted and entered into a database."
For crying out loud!!!!! We don't even fingerprint all of them? What a joke! DNA, fingerprints, photographs, and we could even have ankle bracelet-enforced detention jobs for them. For goodness sake.
I spoke too soon. The BP *might* fingerprint them but they are not entered into the Justice system in the sense that if they contest immediate deportation (which is rare) and lose they can be sent to prison if nabbed a second time crossing over.
