Except Canadians. Unless they're NEXUS pass holding Canadians, in which case they have been fingerprinted. I just got fingerprinted this weekend for a NEXUS pass; my fingerprints are apparently "perfect". The US CBP agent taking them advised me not to take up a life of crime, as I would be caught very quickly. Or at least to wear gloves.
