Words of advice: don't go too deep on the inconsistency angle. The TSA loves to use the "designed inconsistency" line. It's a "cover your butt" line from the TSA to answer the complaints from travelers about inconsistency.

If you search this forum (I'm too lazy to do it right now), search for a thread started by user name AA2070 and read about his experience in Boston. There, the Federal Security Director used the "designed inconsistency" lie to cover the butt of him and his workers.

There is a TSA person who regularly posts here who has specifically stated there is no "designed inconsistency" in the standard operating procedure.

Your girlfriend is likely going to run into a bunch of dead-ends with the TSA, because they do not like to cooperate (as would any agency or company) with negative press.
