This is nonsensical.  From the time that a person looks at your identification to the time that you go through the scanners, there is no tracking of individuals to associate the body type and DNA information with the ID provided.<p>Depending upon the airport, people can go from the ID checks to up to a dozen different lines with no ordering of people as they go through the scanners.  Then on the swabbing side, there&#x27;s no checking of ID once again.<p>If their intent was as nefarious as you claimed, the TSA would have changed the way you move through security in order to properly correlate the collected biometric information with ID.
