After further analysis, Cho is Red John. How do I know this? Ahahahahaha! It's simple. Back when Neil Armstrong landed on the moon, it wasn't determined whether or not alien life was found. Recently, with the release of Transformers: Dark of the Moon, classified information of the transformers space ship was revealed. This determines that Halo Spartan warriors exist in this universe. This also proves to us that the Batman's parents were killed by The Kung Fu Panda.This proves to us that Batman is a big fan of the Krabby Patty. This also makes me believe that the Bird isn't the word and this that Cho is actually a pickle sandwich.
