He also was, you know – again the best I can do with this sort of journalism when you can’t see everything, you can’t see behind every wall, and not everyone says everything you need that – in order to put the story together fully.
But I can just put the facts next to each other, and the facts next to each other are that here’s a guy that worked on cardiac wards administering drugs that regulated heart rhythm and stress levels, and everything else, and also very possibly didn’t genuinely feel the sorts of wild winging emotions that you and I might feel thinking back on murder.
And put those things together, and you end up with a guy who doesn’t register on a polygraph.”
