If they're both in the same Congressional hearing, Bruce can ask them pointed questions which they would be compelled to answer. This means he could theoretically ask them questions that pertain to the lawsuit that they would then have to respond to, without the benefit of counsel, as they say.
I still think it blows ass, and it's a cheap maneuver to keep the mongoose out of the snake pit.
What power do you think Bruce has to compel them to answer questions?
It's up to Congress whether the TSA is forced to answer a question, and Bruce Schneier is not a member of Congress, he was just going to testify before them. He has no special power over the TSA.
He has the special power where he can formulate and present a question that is intriguing enough so that Congress might break out of their daydreams about what it was like being a kid in the 20s and how these people just sit here and bitch when they really got it so easy long enough to think, 'hey, this scraggly looking feller has a good question. Maybe we should make the TSA answer this one since it sounds intelligent and we can't understand it, rather than trying to come up with questiosn of our own.'
