It's the way he looks at a suspect upon interrogation. It makes one look guilty, when there's nothing to be really guilty of, or when it's "guilt" that doesn't have anything to do with the case they're trying to solve.
Either way, his stare makes one too self-conscious. Like he's dressing you down, reading your soul or something. It's so uncomfortable.
I'd be a nervous wreck if he was around and I was being interrogated. I would much rather have Jack Bauer interrogate me than Cal Lightman.
Do you like Cal Lightman's style?
