Most American airports, especially those with international connections, routinely videotape all passengers. I can't cite a source for this, but I think it's common knowledge (not that this means its true).
There was an article in a recent New Scientist (maybe last week) that mentioned the use of infrared scans of faces to identify people since its very hard to change the thermal image of your face by surgery. The plan is to scan every one passing through the airport and forward the image to the FBI (or whoever the local cops are I guess, but it said FBI) and they check out thier database of know terorists (and cypherpunks) and it rings the local gaurds if they get a match. I can try to find the whole article if anyones interested.
