Red John is a Smart guy who had an entire organization at his feet.They can cover his tracks.By himself he is just a poor old man.I agree that Mcallister is not the red john type at all.
In the 6x02 when jane breaks into the room with bertram mcallister and reed, the moment he mention Red john and the murder of sophie jane says "Red John killed Sophie miller 'cause im closing in on him" In that scene there is 2 cuts, 1 from Mcallister face and the other one from jane's perspective.Jane is talking about the murder and Red John, the serial killer psychopath does not show pride at all, he crosses his arms (wich is defensive).
Kirkland was absolutely perfect, even the voice sounded like he was trying not to be Red john voice.B heller wanted to mess with us and surprise us, but eventually he messed with his plot, turning it inconsistent.
Good lord, he loses rock paper scissors,a and he claims to be psychic? Please lol
