I'm not sure I understand the bit about the Iranian with Anti-American views. Was this guy a pilot flying for them? I can't imagine it could have been just a passenger roaming around or there would be no proof of the allegation since there can't be any record of that (certainly not of the political affiliations of anyone who might have strayed into the cockpit) beyond hearsay.
If this guy was a pilot then this is more worrying. Is the TSA going to sanction any airline allowing people with Gulf-nation heritage and a dislike for Dubya's foreign policy to fly? How about the companies that dry-lease aircraft to Islamic states? Are the thought-police going to interrogate anyone flying to find out how they feel about America? Maybe Boeing ought to be sued for selling aircraft (potential weapons of mass destruction) to Saudia, Egypt Air and Emirates to name but three.
