Being surprised that an expert in dishonesty is dishonest is like being surprised that a lot of pyromaniacs become firemen or that a lot of pedos become teachers and priests - it's something they spend a lot of time doing and thinking about, it makes sense that they'd want to do it for a job if they can. No, I don't think spotting this pattern makes me smarter than everyone else.
you're implying that an expert in criminology is more likely than non-experts in criminology to commit crimes, and similarly "more likely" for the other two examples?
