Mac believes in following the evidence, not trusting to intuition. He looks at a crime scene (and often the world) with Veneziano's theory of quantum physics in mind: Everything is connected. In Mac's mind, if he and his team can just figure out the connections, then they can solve the crime. Only once does he state otherwise, when he and Lindsay Monroe are called to a corpse sitting on a Central Park bench, whose death at first seems inexplicable to Lindsay. Mac proceeds to show his cause of death by saying, "Don't quote me on this, Lindsay, but sometimes...the man's severed head not "everything's" connected."
