My second question has to do with customs operations.
Mr. Miller, I think it was you who mentioned the importance of crossing the border more quickly by being preauthorized. You also talked about the NEXUS program.
Isn't there a danger associated with what we might call the bar code? We can use bar codes on material items such as canned goods, but humans are another thing. We're talking about fingerprints and iris photographs. I agree that we need to provide security, but we also need to respect rights and be able to move more freely. People don't necessarily want to be filed in order to move more freely. Is there not a problem with that?
