I have interviewed 100's of people in my career and I must say, when I first heard about this case it was by way of viewing the interview, and my first impression was "this guy isn't lying". I have watched body language analysis of his interview and I wasn't impressed with the assumptions made of his behaviour, particularly when no baseline behaviour video was able to be referenced. I have not studied the presented evidence, although I have read and heard about many various issues with the evidence, lack of evidence and statements provided. Just looking at how DH presented during the interview, I'm not convinced of his guilt. This interview may be the one exception in my excellent history of determining guilt of which I have been very proud.
