I honestly don’t like the idea of RJ being Brett Partridge because in my mind Red John is manly, sophisticated, has many friends, and is meticulous.
I don’t see BP as RJ because he is not lovable as a person, an we can all agree that the followers or RJ see in him as a God like figure, protector, and are willing to do anything even to take their own life for him.
And Brett Partridge is not someone that would make you do anything of that magnitude.The killer must be physically strong, evil eyed yet mentalist like to get people to do what he wants.
Brett is boyish to me, and has really weird fascination with RJ, i see him as RJ fan but not RJ himself.
Red John must be manly, sophisticated, to have a lot of friends, to be well read, to me patient enough to wait for the perfect moments and to do such heinous crimes.
To me Red John is ether Sheriff Tom McAllister or Gale Bertram ( although Ray was the one I originally suspected at the beginning of season 6).I would be satisfied with any of the final five (now 3) suspects as being RJ, but not Brett Partridge, simply because Red John is characteristically similar to Patrick, and I don’t see BP to be shoulder to shoulder with Patrick…..

So, I noticed something interesting about the suspects this year.  The Sheriff is the only one of them who actually gets along with Patrick.  Bertram finds him frustrating as always.  Reede accuses him of murder.  Haffner pokes at him saying "We study you in visualize now," calling his blind struggle against fate so fruitless.  Partridge seems generally upset with Jane's coldness towards him.  Stiles is annoyed with Jane and doesn't want to meet with him.  "What's so damned important?!?" he says.  Oh and Kirkland tries to torture him for information.  :)

Only McAllister is friendly to Patrick.  He asks Jane to call him "Tom".  With regards to the case in Napa Valley, McAllister tells Jane he truly appreciates him making his job easier for him.  He saves Jane's life, even.  Then proceeds to tell him "I'm at your disposal anytime."  When it came to rounding up the suspects, the Sheriff doesn't protest or debate about meeting.  He agrees almost immediately and then asks, "This is about Red John, isn't it?"

I find this odd considering how little the Sheriff liked Jane in season 1.  He was immediately annoyed with him.  He asks Jane curtly, "What exactly is it that you do?"  They play rock paper scissors and Jane beats him repeatedly, making the Sheriff angrier each time he loses.  So why does McAllister like Jane in season 6, then?

Here's my theory;  Red John initially hated Patrick.  He called Jane a money-grubbing fraud and killed his wife and child for slandering him on the news.  However the farther we get along in the series, it seems the more he has grown to respect him.  He winds up saving Jane from the copycats, offers the hand of friendship by sending Lorelei, and even when the 7 suspects are revealed, RJ doesn't kill Jane.  Instead he challenges Patrick to catch him.  That's why I think "Tom" gets along with Patrick in season 6.  He is Red John, and over 6 years of cat and mouse, he has found Jane to be a worthy adversary... and probably the closest thing he has to a real friend.  He has many followers but no one has the guts to challenge him like Patrick.  Red John needs Patrick, much like the Joker needs Batman and Moriarty needs Sherlock Holmes.

I think the list is the RJ did Jane ... because he could not guess as psychic RJ hates that. Patrick is again manipulated by Rj.
Rj is the sheriff all over the profile block Rj is the mentor of Dumar = Marshall Hardy
heller said to be like looking for wally 2x10 watch the driver
Sheriff is the one who says "hi patrick"
in a poem by W. Blake is a phrase
Among the lambs, dressed in white,He walked with her ​​Thomas in sweet delight.I cried with joy, like a dove I mourn;Oh! When will there?
When RJ saves PJ look at the shoes and then shoes look 6x03
Episode 4x24 end the police car look at the smoke leaving the desert comes not from the street ... a sting operation by the cbi-fbi
It smells like pine
He is mar = marshal = sheriff

Hey guys,
I have a link to very good article about the Red John episode that give A LOT OF SPOILERS if you read between the lines.

Red John is someone from the list (3rd paragraph) sorry imdb and mashburn
RJ and Jane will be face to face,1v1 no cops,anyone else than those two
Patrick would be a wanted man 2 years after so I think he killed RJ in 6x08 and hiding himself from cops
Cant wait!
Thanks

To all of you that think that Brett is Red John:

Brett is not Red John. He is more like a fan of his and a follower, I don't see him as someone that can make you do anything let alone to kill for him, and we all know that Red John has that kind of power. Do you really see someone like Lorelei to fall for a nerdy guy like Brett.......No, he is to geeky and twilight looking to be Red John......Red John is a manly man!

My money is on McAllister!

I think that Red John is Sheriff McAllister 

He is the only one besides Brett P. that appeared in the series in the first season, and Heller mentioned in one interview that he knew who RJ is going to be since season 1. 

His physical appearance is a match to the RJ description:
- He is under 6' tall 
- Not muscular but in good physical shape and strong handed 
- He appears to be middle aged
- He is calm and patent
- Good whistler 

He is a hunter and stated that he hunts -" Anything with a face is a fair game".
Patrick noticed that he moves very quietly in the episode - Red Wedding
He is friendly to Patrick and has stated multiple times that - he is always available if Patrick needs him. 

When Lorelei said to Patrick - "I don't know how you two didn't become friends the moment you shook hands." I imidietly thaught of the first time they meet. McAllister was intrigued by Patrick and you can really see his playful side when they "shook hands" - played - rock, paper, scissors.

Plus the actor that plays the Sheriff -  Xander Berkeley is a really good at playing bad guys. 

I theorize that Jane will be able to kill Red John and walk free because the secret Tiger, Tiger cop organization will help him out. That's the only reason, besides providing a new base story line once Red John is wrapped up, for the producers introducing this new "enemy". Red John is as much a pest, it seems, to Tiger, Tiger as he is to Jane. The three with the tattoos are clearly hunting Red John as well.
