Oh, my.
That was just .... harsh ... and callous.
I can't bear a host who would insert loud laughter at the witnesses who were there that day, because they "think they are defending the government". A man who believes that instead of using a shredder, the government would kill all those people, including his cousin ... who kinda... sorta... worked with top secret confidential documents .. and laughs at that. (I would be certain that most documents in any government building - let along the Pentagon - would be top secret confidential).
A despicable demonstration of how to summarise things in terms of a personal agenda and ignore or sneer at anything to the contrary.
