I'm down with the RJ=Rigsby idea. He did show many strange things about his personality in the show. It always stuck me weird that a big dude like that let so many people make fun of him. What did Rigsby mean when he threatened FBI O'laughlin? We assume Rigsby is trying to protect Grace, yet the threat is a little more... cryptic... than what one might expect. Just sayin. 

Well, my thoughts are that Jane/jisbon has yet to decode the blake society list, and thus I am in favor of a Rigsby slasher ending to this lost television show. 
Anyone find it bizzare that Rigsby instantly knew where Jane buried his wife. The "Red John" S6 has Rigsby in the back of the truck stating clearly and without hesitation the exact name of the cemetary where Jane buried his wife. This is one strange thing among many strange things Rigsby does while in the back of the truck... calmly sitting the back of the truck. 
The only thing that makes me think that RZigsby is not RJ is the the blind lady says that RJ is under 6 foot tall. Rigsby is clearly over 6 feet. However, I do understand that RJ had many helpers. 
Oh Wait... Lorilie Martins also hits Rigsby over the head when she is going to kill her victim. Would Martins hit her beloved RJ over the head??? Methinks, not!
Aside from those two problems, Rigsby could easily be RJ.  

Yea, Yea... Kirkland was a good choice for RJ, and so is first CBI chief, Minelli (sp?), but I truly think that RJ is best suited for a split personality serial killer type dude like Rigsby. I personally think that it would be cool, very cool. 
I understand that McAlister was played by a good actor, an actor I consider one of my favs, but the sheriff just didn't work for me, and I think for a lot of other peeps. Most of us are even wondering if Gotham will be dropped on its ass in similar fashion, I mean... who hires the Fresh Prince's wife for a criminal anyways??? Seriously?
Also, Bertrand was a good choice, a bit to old school, but at least he would have made a good character because of the direct influence over CBI agents. AND, let us not forget the Head Cheese of Visualize. One cannot go wrong with Brett Stiles/Caligula as a serial killer. 
Soooo many possibilities, so many other viable options left out to the elements, and we are left with cowboy boot wearing, sheriff McAlister, WTF?
I just want to say, this new jack-booted FBI circle jerk is boring and depressing. Witches says that the last episode is named "white tulips", well I know where Heller can plant his white two lips. Im fucking depressed... Why not make Cho, the literary "chinaman", RJ, and send my over a cliff? 

Keeping with the current theme of the board today....
For will the thrill.....

Red Rigsby

Rigsby and Van Pelt are in the last episode. I have two possible options as to why they are in the finale.
1-Rigsby was definitely a choice for Red John by the writers. The clues are immense and impossible to ignore. Whether they moved on from him being Rj is another question. But no doubt he was a choice.
-Rigsby is Derrick Logan. A troubled teen who was bound by black tape and humiliated by a popular girl in front of his whole class.

Logan later turned to drugs but joined Visualize and got clean. People thought he died.
He started killing only red haired women and of coarse Rj always uses black tape to bound his victims wrist just like he was in high school.
He killed women just like the high school girl who tormented him.

-Rigsbys dads episodes are tell tales of horror.
"Weakness is in the eyes boy" is Mr Rigsby's favorite line. Reminds me of the Rj smiley bleeding from the eyes.
Mr Rigsby pulls out a knife and it scares the shit out of Wayne even as an adult. He most likely saw that knife many times in childhood.
Its a small knife and exactly the type Rj uses to kill.
-We really don't know who killed Todd Johnson and set him aflame.
We assume Olaughlin did it but Rigsby was a suspect for a reason.
-The Bertram usb was definitely not Bertrams. No way he held BA incriminating evidence like that and just left it there. He had no idea it was there. Rigsby wanted Jane to crack the code and take down the Ba. Just like he did.
-the Haibach stuff is insane.
No clue or proof that Haibach tapped all Cbi members, killed La Roche, Ardilles, or broke into Rigsby's house!
Haibach only captured Gvp when he learned he was a suspect.
Maybe someone paid Haibach to capture Gvp and let him know he was a suspect.
HOW ELSE COULD HAIBACH KNOW HE WAS A SUSPECT!?
-Of coarse the 5 shots to the chest of Rigsby and him walking around like he is fine right after was so odd.
Something is up with that guy!

The way Jane took down the Ba seemed too easy for me.
This high powerful organization was taken down because they hired a random Pi to tap Cho's desk in broad daylight. Also Left her alive long enough to give Jane the tattoo clue.
Jane was given clues like breadcrumbs until Macalister was finally on his lap.
Seemed like someone was leading Jane to the Ba all these years.

OR
2: Rigsby and Gvp are in the final episode for a Jisbon wedding....

True enough, Rigsby is in the last few episodes, and thus the world will know what kind of a creep fuck serial killer he can portray on screen. HarvyHammer is wise in suggesting the great red dragon from this proper educated actor, Owain Yeoman. 
Rigsby has:
Daddy issues===
Women issues===
Self esteem issues===
friend/social issues===
A hidden past of humiliation where he was stripped and photographed by fellow students===
acrophobia===
profound out-of-character insight into the criminal mind shown to us on various occasions===
bizzare and unnatural respect for those that do not deserve respect.
One has to remember that Rigsby was questioned by LaRouche about the guy set on fire in the jail cell. No one ever confirmed it was Van Pelt's FBI football hero boyfriend. 
It's like this... Rigsby was a geek in school and was humiliated. He became a drug addict before joining Visualize (TV version of Scientology). Then, Rigsby becomes the great red dragon we all know as Red John and joins the bomb squad in San Diego and then later CBI where, coincidentally, Patrick Jane picks up his trail. The story from there is laid out before us. Red John is Rigsby, and Rigsby is merely the truth hidden in plain sight. No one makes fun of Red John, or they get dead! Think about it. 

Wayne Rigsby is still Red John.------ GO BACK AND WATCH THE EPISODES WITH RIGSBY IN MIND. He is perfect.
--------------
Also, the actor, Owain Yeoman, is the only actor on the show that could actually pull off a great red dragon (Royal Academy of Dramatic Art graduate). Keep in mind that Rigsby is all too eager to jump on people from second story buildings -- a true measure of an RJ trying to compensate for being acrophobic -- motivated only by a love for Grace. -----------------------Just look at the Rigsby's moments that are calm and reserved, that is, when Rigsby talks as a real person and not a drone in the CBI machine. He is a creepy muther fucker, and if the writers would only show Rigsby down in that red barn, we would have a wonderfully mind-bending end to the series.--------------------------- By-the-way, Bruno Heller is the only serial killer true fans know of to date. May Heller drag his tongue across my sweaty asshole. Happy Holidays! 

so if we are going to pretend that RJ was not a pathetic small town sheriff who was afraid of birds, who was an avid hunter but carried the worlds weakest gun the meet his nemesis, who couldn't manhandle GVP, who had wicked awesome PC hacking skills, then we need to explain why he hasn't killed in nearly 3 years.  serial killers don't just hang up their blades and call it a day.  they are addicted to killing, much like the way that formercop is addicted to being a raging douchebag.

maybe RJ has put a hold on killing to concentrate on his hew wife and baby......
