Bob Kirkland was first on my list, now not so much....here are my random ideas.

So reede smith gives kirkland a paper to the safe house, now why would he do that if he wanted to kill him anyways, doesn't make sense  and exposing that paper (which we think has the address).

So here is a thought, reede wants to turn good maybe? By helping kirkland, but at the same time reede needs to convince the driver that yup i am with you.........we will know laters about that.

Here is an interesting theory i came up, the word Stiles in Brett Stiles actually means an arrangement of steps that allows people but not animals to climb over a fence or wall......is that a clue that he is superior than others??

Lastly he is the only one that has access to anyone, anything he wants, all world leaders are being leaded by him in visualize...BUT isn't that too ambiguous  ??

My take is Bret Stiles.

Season 01, Episode 23
Rosalind description of RJ:
- Under 6 feet tall 
- Not muscular, yet not soft either 
- Short straight hair 
- A gentle voice 
- Rough strong hands 
- Smell of pine, soil & earth 
- Like listen to piano, specially Bach. Cos of the rigor. 

Season 05, Episode 08
Lorelei Martin mentioned:
Jane and RJ are so similar that she wonder why they did not become best friend when they shook hand.

Season 06, Episode 03 
Dr Sophie Miller recorded:
- Middle age man in good health 
- No prior psychiatric issue 
- No family, but has many friends 
- Well-spoken & show good posture 
- Excellent whistler 
- A hint of narcissistic personality

If based on the above.. 
Stile and Smith are under 6 feet (Jane's height) with short straight hair. The rest are above 6 feet (taller than Jane) Stile is not mascular yet not soft either but Smith is round. Haffner could be but he got workout and taller than Jane which means he's above 6 feet. 

Middle age can refer to Bertram & Haffner while Stile still can consider middle age but McAllister looks old where Smith looks young. Stile have no family but have tonnes of friends and followers. 
How did Stile knows where RJ keep Kristina Frye? How come he can have such power to help Lorelei Martin escape federal prison and Martin know RJ will help her out?

Stile is well spoken. And having great confidence posture which may regards as narcissistic personality. If not, how would he manage to convince Visualize followers?

Great whistler, anyone can be but not all the suspects having the other important traits mentioned by Rosalind and Sophie. (This could be a distraction from scriptwriter. :p ) Among all these men, only Stile have few pleasant encounter with Jane and had Jane help him clear his name on 1 occasion and he help Jane on several occasions. RJ sees Jane as friend or comrade and wants to befriend with Jane which I'm thinking if he can help Jane, he will. Eliminating obstacle for Jane creates a bondage for RJ to reach out to Jane.Hence, my conclusion of RJ is Bret Stile.

Side tracked a bit.
Tyger Tyger seems like another coded word from 604 onwards. Initially recited by RJ to Jane personally. If The Tyger poem is meant to show something to Jane.. Could RJ be testing Jane's ability to believe whether there are really something which Jane do not believe BUT DID actually exist out there. 

I.E. Psychic ability? 

Tyger Tyger, burning bright 
In the forests of the night,
"Tyger, tyger" the repetition creates a chant-like mood to the whole poem, which contributes to the mysteriousness. Reading it, you can’t help but get the feeling this poem is about way more than the biggest cat in the world. 
"burning bright, / In the forests of the night"? Tigers don’t burn. "Burning bright" may describe the appearance of the Tyger (tigers have fiery orange fur), or it may on a deeper level describe a kind of energy or power that this Tyger has. The Tyger's presence in "the forests of the night" further increases the mystery and power of the creature – it’s elusive, while at the same time burning with some sort of inner force.

What immortal hand or eye
Could frame thy fearful symmetry?
The "immortal hand or eye," symbols of sight and creation, immediately conjure references to a creative God (in pretty much all cases with Blake, "God" refers to the Christian God). If this is so, then questioning whether God could do anything is a direct attack on the omnipotence of such a God.
To "frame," here, is probably to contain, kind of like putting a picture in a frame. When you frame something, the boundaries are clear, the object isn’t going anywhere.
"Fearful symmetry," is a very nuanced quality to have. "Fearful" references the scariness of a tiger, an old notion of really big, powerful, mysterious stuff that terrifies us because it’s big, powerful and mysterious. The first BIG example that should come to mind: God, or the divine (that stuff is big and powerful and mysterious).
Symmetry is a classical quality of the divine, as well as the defining factor of artistic beauty.

With Visualize in mind and the poem.. Its hard for me to jump out of the box and think of anyone else other than Bret Stiles. Of course, Haffner could be another high possibility of the real RJ as he's also a member of Visualize for long time.. We shall see in 605..

while there's lots of "evidence" that we "know", the only thing that we truly know is that Red John employs a seemingly endless supply of disciples to carry out much of what he needs done. Is it too far a stretch to assume that the men that Rosalind Harker and Jane's psychiatrist weren't actually Red John either?

Red John's disciples have also proven to be willing to sacrifice themselves for him - carrying out his orders even though those orders will likely get them killed or caught (or require them to kill themselves). Sounds kind of like extreme religious devotion... cult-like devotion. As Bret Stiles already runs a cult, it kinda seems to be the most logical conclusion that he would be Red John. A cult leader that inspires cult-like devotion; wouldn't that fit the bill of being a disappointment (as per Bruno Heller's suggestion about who RJ turns out to be) being that it's a fairly obvious connection?

We now know that Red John does in fact have a network of disciples throughout law enforcement; but was that really all that hard to believe? We've seen people acting on behalf of Red John within CBI all along. In Red All Over (a telling title?) we saw a cop on the scene tamper with evidence that connected a murder to Visualize - perhaps a coincidence, but it could also be a bit of foreshadowing in suggesting that Stiles' organization has followers everywhere (just like RJ).

We also know that Kirkland's brother got help from Red John to kick his drinking and such, which is kind of the type of thing that Visualize does.

On a practical level, I just can't see Red John, a criminal mastermind of this huge organization of disciples (and that's only counting the ones that we've seen), having a day job. Stiles has more control over his schedule than any of the other suspects. The rest all have to punch a clock, so to speak. They have responsibilities that would be hard to avoid if need be, whereas Stiles is at the top of an organization with many loyal followers under him; he can literally set his own agenda and do what he wants, when he wants. He also has more than enough resources at his disposal to carry out whatever plan he might wish to execute.

On a personal level, if I were the creator of a series that was built around one man's search for revenge against an incredibly smart and resourceful, yet utterly diabolical killer, I'd really love for that killer to be played by the guy from Clockwork Orange. That really does seem like a great option if you have it. Just saying.

It's more a question.If the ''cult's'' people identify each other with ''Tyger Tyger'' why Brett told to Teresa ''Tyger Tyger'' before he died ? ^_^

Even though we seem to be getting closer I'm finding it more difficult to narrow down the suspect pool.

After last night's episode- and the tyger tyger conspiracy I think that Sheriff McAllister, Reede Smith and Gale Bertram are all part of this law enforcement underground group. I do not believe they are red john. I believe Red John may have instigated this group that may have convinced them they are all part of a great mission but I don't think they know he is part of it. 

That leaves Brett Stiles and Ray Haffener. I have always liked Ray so my gut feeling is that it's just not him leaving Bret Stiles. I think with his connections with visualize he may have planted or started this tyger tyger group within law enforcement seeing as Ray Haffner and probably a lot more people have been initiated into the cult.

So I guess we shall see!  

Despite my name, I believe it is Bret Stiles, and for many reasons. It seems sort of obvious, but I could be far off.
1. We haven't seen him at all(once?) this season(6) if he is RJ, he may be wanting to lay low for a while. Or Bruno H is pulling our legs!
2. Visualize! Up until now,6.4, it has lead us to believe that RJ is with a group, Or a group of people himself (he is mar, he is many idea) my idea was that visualize is the cover up or some other group that BS is also in charge of. The way to know if you're in the other group inside visualize, the phrase Tyger, Tyger. In 6.4 they prove that Tyger Tyger is the phrase they say to show who they are. At the end of the episode (SPOILERS) the guard says Tyger Tyger, showing that it is more than just the 7 suspects in the group. Bret Stiles is in charge of visualize, which is a cover up for the RJ group.
3. Evidence from tape. The tape for the therapist says he is shorter than 6 foot. Bret is, and he is older than 30. To have commuted the crimes he would have to be older or at least 30(look at clues for this website) also, I could just see him being a whistler ;).
4. IMPORTANT! In 6.4 they kill bob Mcallister this proves it can not (NOT!) be the great red dragon idea. Now 2 of te suspects are dead, and the theory states only one is "dead". This discredits it, and shows that not all the suspects work for RJ.
IMHO, Bret stiles is red John. He hasn't been seen for a bit, he's old enough, and he is smart enough. He can use visualize as a cover up, and he is the only 1 of te 5 I could see being RJ.

after a few years of watching piece by piece not much a tv dude, I got hooked on the mentalist last year, this summer got my self season one, and two, so thats all I've seen for episodes in sequence but I'm sure I've seen at least 80% of the episodes, and all my evidence points to Stiles, except the fact that that blind women says the age of him to be much younger than Stiles, maybe it wasn't Red John him self that met that women but one of RJ(Stiles) closer disciples(maybe heffner),

but a good mole for RJ if BS, is in the first season episode "Miss Red" you see a young feller (cop/guard) that tried to stop that girl who made fun of his shirt to get away, that young cop was named "Stiles" hence Brett Stiles way to get inside info on CBI and thats all you get to see of stiles in the first season,

in the second season you finally meant Stiles than you see Red John in the last episode

Stiles is Heffner's leader

Stiles is damn good at manipulating others

and blah I could go on, but from my point of view Stiles is the one who can easiest pull off everything Red John has so far... And get away with it.
