STOP FUCKING SAYING IT IS JANE, THERE IS TO MUCH EVIDENCE TO DIS PROVE THIS THEORY. 

ITS NOT FUCKING PATRICK JANE THERE IS TO MUCH EVIDENCE TO DIS PROVE THIS 

I think that after episode 5x16 it is 100% sure that Patrick Jane cannot be Red John. If he was then Lorelei would have killed him. She had the means and opportunity. He is NOT Red John. End of story.

Patrick Jane, has been known to have a past where he went mental, I believe that he was once Red John. However after becoming so upset with killing his wife and daughter he has lost control over his own sense.  His mind has taken over and he went crazy,as seen in flashbacks of season 1. As you see in corner of the wall there is a red John face perfectly drawn. I believe that his mind took over his body and he became self obsessed with Red John. As Patrick Jane is a con artist I think that Jane has conned himself.  

For some reasons i believe its Patrick who killed Panzer (San Joaquin Killer). Before that episode, every one believed RJ was killed by Jane. No point for RJ (if he was alive )to reveal his identity immediately after the talk show.

he is always hiding isnt it ? its good for RJ to stay even low from FBI after fooling around with Jane into killing of Timothy Carter as RJ. 

Why will he reveal himself to kill him ? when he has a chance to operate even low.

From that episode we know that PJ really hate Panzer and wanted to kill him.         
 

SHAKING HANDS WITH THE DEVIL

     Shaking hands with the devil can mean that you have subconciously or conciously made a deal with someone. Shaking hands with the devil also means getting to know or meeting evil for the first time. Also, partaking in evil for the first time.
      
      Now think about Lorelei's quote from character perspective.

    "I only wonder why the two of you didn't become life-long friends the moment you shook hands..."
      
      Red John's followers obviously hold him in the highest regard, as in the worship of a deity or supernatural figure. .
God,Devil..so on. They are willing to do his biding.
(die for him too? Tim Carter anyone?)....
      Case and point: The "shaking hands "clue"" doesn't rule out
PJ as RJ. Lorelei may have slyly been referring to PJ's initial transformation or mental break into the murderous Red John.

      PATRICK JANE: "I'm not under any curse."
TIM CARTER "Doomed to an endless, angry search for a vengeance you'll never have; I would call that a curse, wouldn't you?"

       THE LIFE WE COULD LEAD
 
    The limo scene: Season 4 finale:
The voice of RJ was that of Simon Baker. A simple pitch correction reveals this. Once again here's the link...
www.youtube.com/watch?v=bq4c7ZSwYh8
It's possible the conversation was scripted/recorded. Scripted through hypnosis...who knows...doesn't matter. Click the link. Listen.
 I'll wait here.
    It's also worth noting during the scene
the voice of Red John says "..imagine the LIFE we could lead..It's a higher path.."
Shouldn't he have said "LIVES we could lead?" Remember scripts are drafted, edited, rehearsed, etc. And ADR could've fixed this if it was a misreading on simon's part. It's no accident RJ referred to himself and Patrick sharing 1 singular life.

         PATRICK'S FAMILY MURDERED WHILE HE WAS ON TV
   
      These scenes had obvious cuts. Were also flashbacks weren't they..
No indication of linear storytelling. Your mind wants to place them in the order you're seeing them. I find it easier to believe it was Patrick Jane acting as Red John who killed them.....rather than believe Red John happened to be watching tv at a particular time, a particular channel, and was in close enough proximity to get there, murder, TYPE and PRINT a letter, all before PJ got home.

        I can't seem to disprove PJ being RJ. And though some people may not want to believe it. Evidence to the contrary keeps stacking up...
Oh no...your beloved Patrick...LOL
            I hope it's him..i admit. Red John killed Panzer after PJ was staring at that blinking red light...
             PANZER to PATRICK JANE: "How can you live with such duplicity?"

Enough of the "oh he has a red boat/shirt/blah blah blah....
    
  I still hope/can't disprove PJ is RJ. More evidence toward PJ than against in my opinion. Mental disorder, hypnosis whatever the case..
  
  I don't think the series will end this way. Too much of middle america would be confused and never get off their tractors again. And too many lonely women wouldn't be able to drool over simon anymore. LOL 
    I think it'd be great though and give simon baker a chance to show off some acting chops...
        

Among all other clues that RJ is PJ , there is also smily face, RJ signature, that have eyes drawn diagonaly , and if u look PJ's eyes they are same as RJ smily. Knowig that killings started long before PJ enterd the scene, in my opinion that makes him the prime suspect.
