 This is a true professional here with actual skill. Did you knowingly conceal Kaley's wear box? No. Okay, so you're struggling with that one a little bit. Tell me why. These aren't clarification questions and they aren't just to check on how a person responded or what happened. Here's an interrogator who is using the machine to establish what we call touch points to dig in specific areas. And I personally think of a polygraph like a metal detector at an airport. It goes off. You have no idea why it went off, but it provides an opportunity for a human to step in and figure out is it an AK-47 or is it a giant belt buckle that we're dealing with here? That's the importance of having these human skills that this guy clearly has.
