I like all your theories about Jane being red john, but has anyone else noticed that Director of CBI Gale Bertram has quoted William Blake several different times. Which red john is doing all the time too. He would fit the age range for red john better he was there just b4 Jane shot who we thought was red john at the end of season 3 then mysteriously no where around after he shots the guy and for there theory of red john possibly being a cop he would have to b high up in rank.
