Another thought... Reed and Bertram are definitely in "the 3 dots tattoo gang" but I don't think either of them has a clue who Red John is. I bet RJ knows who they are and that they are in the "3 dots tattoo gang." So is there three different groups here?

3 Dotters that say Tyger Tyger
Red John Followers
 or do you think the three dotters/TT are all the same and headed by RJ?

I just dont see RJ being a head of a conspiracy organization. Im sure he has followers, but hes a sociopath serial killer not some group builder...

If you agree with my thoughts that the 3-dotters are not associated with RJ, what do you think their role is?
Are the hunting RJ and his followers? Are they just a corrupt group of people throughout law enforcement with another agenda not related to RJ at all?
