I think people in law enforcement would be the real experts on this, and I would defer to them. Alan's a world class interviewer, but I have done interviews, and know people who have done interviews as the key component in their line of work, and our acknowledged tendency is to overestimate what we know and can predict about an individual from the interview.

Law enforcement would know whether to believe four or five hours of face time or hundreds of hours online. I defer to anyone with that experience.
