If I get any beef, I just grab the TSA guy by the shirt collar and say..."I know you you better let me through, I will tend to start kickin your behind". That usually solves things.
This is what I was referring to, as in doubting you would actually do that. For the above stated reasons. And yes, it's an old article, hence my disclaimer of saying "Supposedly enforcement of this has been suspended, but I would not bet my career on it." However, the FAR's are current as I'm sure you know.
