The job of ensuring airports are secure is that of the FAA and TSA. These organisations should be and presumably do auditing to ensure that proper procedures are in place.
These journalists should be prosecuted and so should NBC. But they won't coz if they were the White House wouldn't be able to get them to withhold tape of Bush looking like he didn't have a clue as one film maker found out recently.
If NBC has evidence TSA and FAA are not properly auditing aviation facilities it should show it, not go after airports in a way that they are damned if they profile suspicious characters and behaviour and damned if they don't.
