Hey guys, 

this is just something I noticed: When Kirkland was speaking on the phone, he was talking to a guy named Tom. Yeah, Tom. I believe he was talking to McAllister.
Kirkland was the one giving orders to Tom. Check out the video http://www.youtube.com/watch?v=sPblDPqw7eQ at 00:00:59, when Lisbon enters her office. I remember Kirkland speaking to Tom in another episode, but I couldnt find that one. 
It seemed like Kirkland was using Bertram like some sort of puppet, when he was talking to him after Lisbon left Bertram's office. Kirkalnd seems like the puppet master behind Bertram and McAllister (propably also behind Smith, who's clearly involved with Bertram and McAllister).

That doesn't have to mean Kirkland is Red John. But it would definitely rule out Bertram, McAllister and Smith. That would only leave Kirkland, Haffner and Stiles (considering Partridge's death).

I would love to hear your opinion about that and maybe you can find the other scence with Kirkland on the phone :-)

Cheers McRob and RedJane :D
