I believe strongly that Bob Kirkland is Red John or is an accomplice.

I think Bob is Red John for many reasons.
Here is a few:
- He never seems to have an obvious expression on his face, he is someone who doesn't feel loss, hurt or regret. A perfect image for Red John. The one time I've ever seen him smile is after he bumped into Jane in the CBI's office. After shaking Jane's hand and saying 'No, but I know you.' he walks off and then glances round with a grin on his face (kinda looks like the smiley face - RJ symbol). And I'd like to examine that he said 'No. but I know you.', he says Jane doesn't know him but he knows Jane. Exactly LIKE RED JOHN. Red John knows lots of stuff about Jane - in season 5's finale he connects with Jane's childhood/origin - but Red John believes Jane knows nothing about him and thinks Jane might aswell give up.
- He is the perfect age.
- He has contacts in: CBI, FBI and Homeland Security.
- He has a soft voice, Red John probably uses a voice changer/morpher. When he says "Thank you." to an FBI agent in a limousine he sounds rather high pitched and that matches (slightly) the voice Red John used when he saved Jane and recited William Blake's 'Tyger'.
- He seems interested in Jane's progress in the Red John case.

Some of the reasons above both fit for how he could an accomplice.

Red John could be an organization of several people though, or Red John is very manipulative, devious etc. and has MANY people under his influence/guide.

Robert 'Bob' Kirkland is an accomplice of Red John

Jane is MORE clever than Red John and knew something would happen to his list so he planted a fake list knowing someone would take it and whoever takes it IS an accomplice of Red John.
Jane wanted someone to take the list so Red John would feel safe because he would know he is not on the list.

This is why Jane was smiling when he saw the toothpick on the floor because he then realised someone had broke in and his plan is now in motion.

That Lorelei died before Kirkland send team to investigate Jane's board does not mean he is not RJ. Let me explain:

He might have recorded more than one video. Like 50 videos for example. Why not? He has all the time in the world.

Then Kirkland kills Lorelei.

After that he asks Lisbon about RJ and Jane and makes Jane feel suspicious.

He sends a team to take photos of Jane's room. He knows Jane will notice that someone broke in the room, and possibly Kirkland's guys, after the conversation with Lisbon in the morning.

He works on the material and comes up with 7 suspects. He chooses the video that matches with possible suspects and gives it to that woman in CD.

Now, doesn't he have the best excuse?  

What the hell was that? Don't you agree that this was a crap finale? 

All the episode was about the 7 names. I personally don't want 7 names, i want action! But this is bullshit. 

I am very disappointed and lost a good amount of my interest in Mentalist. We have already been analyzing characters for years, what good does it do to analyze 7 of them? Knowing RJ knew Jane's memory doesn't help us at all, as we cannot connect the dots.

Well, this finale was definitely for an ordinary person, not mentalist enthusiasts and i feel insulted.

I think for some time now, that RJ is Jane's father. He's upset with Jane (obviously) and wants to hurt him. That would explain also how he knows so much about Jane, his past, ans the way he thinks and solve cases. BUT... And that's the trick of my theory... I think Bob Kirkland IS Jane's father !!! Remember before killing RJ's disciple at the hospital he said "do you recognize me?" ? He had a surgical operation of the face ! He changed his identity I think. When he shook hands with Patrick, Patrick said "do I know you?" Because he reminded him of someone somehow. That would explain too why RJ has a obsession with Patrick and wanted him as a disciple and friend back in season 3 and 4. Maybe he wanted his son's back. And then Bob said "no, but I know YOU"... So I think now Bob alias Jane's father is Red John.

What do you think ?

That guy who was incharge of that daycare was in the hospital who knew Red Jorn. Bob kirkland told him "Look at me closely, do you know who I am?" so clearly Bob kirkland has a PERSONAL connection with Red John.  Maybe Bob Kirkland is Red John with plastic Surgery and the guy in the hospital bed didnt know red john had plastic surgery so when kirkland said look at me closely he wanted to make sure he's unrecognizable as Red John. Then he killed him to shut him up.

WHAT WE KNOW ABOUT RED JOHN SO FAR:

Red John is most likely a man. He appears to be a Caucasian, and is a white person as described by HaleyRed John has an average height: Rosalind described him as "just under 6 feet tall"Red John has short straight hair (as described by Rosalind Harker)Red John either has or puts on an odd, high pitched and soft voiceRed John should be older than 30 years (since his murders date back to the 90's). He used to work in the circus, he has mind reading tricks (like Jane) and is very clever. He is also cocky (but may not show it). He is controlling (he got upset that Jane broke the rules thus he "changed" the rules thus episode name Red Johns Rules). ( The guy who didnt get the child in Red Johns rules said that maybe Red John has powers like him and his family and its non fake, he could know Red John or Red John could be in his family).

He has gone by the alias "Roy Tagliaferro," the name by which Harker knows him. This name may be related to his work with iron, as Virgil Minelli first realizes "Tagliaferro" means "cut iron" (edited 25. april2013 Taglio is cutting and ferro is instrument - seems more like that then cut iron) in Italian. He has also used the pseudonym "DR. JOE N.H." (an anagram of Red John) or "Doctor Joe in New Hampshire" when accessing the CBI secure network.He appears to be caucasian. This from the appearance of his bare hands (drinking tea in the season 1 episode "Red John's Footsteps") which appear to be that of a Caucasian male.He is literate in the poetry of William Blake (Red John quoted one line from the poem The Tyger to Jane at the end of season 2. This same line was spoken by another Red John associate, Todd Johnson, directly to Jane shortly before Johnson died.)He works occasionally with others. His first known accomplice was named Orville Tanner, though Tanner died in prison. Tanner's son, Dumar, appears in the episode "Red John's Footsteps" as another friend of Red John. Other accomplices of Red John have been revealed as the series has progressed, including some inside the CBI itself (Sam Bosco's secretary Rebecca in the episode "The Scarlett Letter"), others outside the CBI who admire him and perform their own murders, such as Todd Johnson (who appears in the episode "Red Moon"), some whose inside information may have provided Red John with detailed data on Jane and his CBI team (such as Craig O'Laughlin who is revealed to be a Red John operative in Strawberries and Cream Part 2), and still others who have been "sent" to speak with Jane but who presumably are not yet murderers themselves (such as Lorelei Martins in "The Crimson Hat".) Each of these "disciples" as Jane calls them ("Red John doesn't have friends. He has tools.") has seemed to exhibit fierce, near complete loyalty to Red John.He may have extensive knowledge of computers, or may employ a colleague with such knowledge to assist him, as he has on several occasions accessed (either through hacking or the assistance of an insider) what Agent Grace Van Pelt refers to as the "CBI secure network" (the first time this occurred was in the season 1 episode "Red John's Friends").In his criminal history, Red John's initial way of killing was to use a handheld linoleum cutter. A "textbook Red John" murder (according to Agent Kimball Cho in the series Pilot), consisted, at that time, of the use of a stun gun to subdue the victim, followed by "binding with tight black plastic ligatures, frenzied cutting and stabbing assault of the torso, and subsequent abuse of the viscera." If his victim is sleeping, Red John is believed to wake them to see the look of fear. Though this was Red John's early style of murder, in subsequent seasons he has killed by other means, including the use of poison and, in at least one instance, a handgun. 

I hope this helps some of you build upon your theories!
