I am still not giving up on Suspecting Rob Kirkland. Tiger Tiger is a meaning from William Blake, the twist is happening now thinking that tiger tiger is a code used by the FBI. I strongly doubt that Red John is somebody higher up in the FBI. Why were they relaying information to the Homeland Security instead of the FBI itself? Rob Kirkland is Red John and i dont believe he is actually dead. he is pretending too. Who in their right mind would torture somebody to extract the truth. I see the truth Rob Kirkland is Red John and his followers are going to help him deceive everyone.
