[QUOTE=IrishDoesntFlyNow;19452068]To whomever it refers, it is silent as to the nature of the "system, method, or procedure" with which a traveler must comply when seeking to enter the sterile area. Allowing for the implementation of a "system, method, or procedure" does not mean allowing for just any "system, method, or procedure".[QUOTE]

The important part is that Ron quoted the blog and the blog referenced rules for screening of TSA and airport employees. The rules developed by the TSA are different for this class of persons than for passengers. Passenger screening is covered under 1540.107.

The rules & procedures for airport security are found in CFR 1542.

Yes the entire mess is vague.
