I'm sure that those 7 suspects are red john all but bret stiles is the boss so it's possible that they could kill everyone anytime when they want.

I know i'm way off most likely but this caught my eye and i wanted to share just in case i'm right about this and it's not a typo first go to (  http://www.cbs.com/shows/the_mentalist/red-john/  )

Now look through all the seven suspects and notice that for Bret Stiles it doesn't say Character before his name like it does for everyone else but like i said maybe just a typo

I think red john is Bret Stiles. (; 

Bret Stiles is red john
he hadn't do all these crimes by his self
there is a lot of people Influenced by his ideology and personality in his Church denomination
Bob Kirkland is his spire inside the CIA he might be a member in his Church

Having seen every episode, i cant say who red john is. For me, there is only two things which must be taking into account.

firstly it cant be the split personality of Jane himself, the episode where Jane is tied up and red john kills his would be killers, whispering "tiger tiger in his ear", rules that theory out.

Secondly, the final episode makes it quite clear that red john is in, or has been in Jane's head. he knew the list and also the memory.

I think its fair to say that the whole show is about the manipulation of the mind, is it unreasonable to think maybe Jane has in the past been hypnotised to give freely information and not remember doing so?

I love the show and pray that it doesn't run too long, with two many twist .. leaving only one option as  an ending, that of Jane in a mental hospital and the the characters being staff in said hospital. I'm of the opinion that the season 3 finally in the restaurant was the perfect ending.

Well, I can't say that I've watched all episodes, but I'm quite certain that Red John is not just a single person, but a cult. Their members are all over the FBI and CBI, which is how "he" gets to know everything, or they are CEOs or such, which is how he funds himself if required.
I think Bret Stiles is definitely involved: Bret has shook Patrick's hand, their characters are similar - they both know how to manipulate people and they both are 'mentalists' (if that's the true saying) -. And he knows about Red John's actions. For example, he told Patrick the location of Kristina Fry.
Please leave a comment below, I want to know if I missed evidence or haven't seen one.

I was re watching all the Bret Stiles episodes and either I missed it but I didn't see him and Jane shake hands, did I just miss it or did they actually not meaning the list can get cut down to six
