I found the comment that points out that having both parties in the same hearing who are under oath and currently engaged in a lawsuit, might find themselves making statements or responding without the benefit of having their counsel present. Then one might turn around and subpoena that testimony into the lawsuit and add it in as evidence, fairly compelling.

That being said, it is how the game is played. If one of your representatives are on the committee I would recommend writing them a note, or calling their office, to express how you think they should oversee the activities of the TSA.

One of the issues which needs more coverage is that Security Theatre is not 'harmless mostly, possibly helpful' it is in fact 'harmful mostly, possibly helpful'. This sort of theater cuts into business productivity, makes folks on the planes grumpier, causes millions of dollars in losses when folks miss planes, and erodes the citizens trust in their legitimate law enforcement agencies. It is not harmless, it is harmful and that message needs to get to Congress.
