Just thinking out loud, in a similar vane. It's entirely possible that this has been reflected on previously, if so, please ignore.
I've been reflecting on CPH's being cornered by the media as he walked to his car. Obviously, under that circumstance, he was becoming angrier and angrier with the questions. How did he react to his own growing rage? By pretending to have a problem with his "defribrillator". Not having "chest pains" but using the word "defribrillator". A medical device, that a working girl/guy would be confused by. Is this how he gets his victims to let their guards down? By pretending to have a problem with a medical device? If he wanted the interviewer to move farther away from his car, why not say "step away from the car". But his "attack" was drawing the person closer to him. Slumping himself over near the ground, the victim would crouch down beside him, and he could quickly and cleanly strangle them.
