> These are professionals being interviewed

They're detectives from the case. They aren't interviewing the same guy over and over, it's a different guy for every case. And, like I said, I've known a few personally who echo the same thing.

Never once have I seen it presented as an interview technique. They will "clear" people based on polygraph.

This could all be theater, as you're saying, but we're getting into 9/11 size conspiracies to keep all of this coordinated. It's much more likely they are telling the truth. If only there was a machine we could hook them up to to find out...

> Many may feel that people ... that's a sign that that they very probably have something to hide.

That's another can of worms.
