SPOILER ALERT!
Some thoughts on last night's episode and the hunt for Red John.
Bob Kirkland hunting Red John himself was a plot point many of us saw coming and I was pleased with the way they did it.  I think Jane was pretty stupid to allow Kirkland to leave without telling him [Jane] anything as he would surely have expected Red John to have him killed. However we still don't know if Red John gave the order or whether Reede Smith was acting in the interests of the newly discovered "Tyger Tyger Conspiracy" which Kirkland was apparently investigating.
With regards to the Conspiracy it appears to cover most, if not all, aspects of California Law Enforcement and has members ranging from the FBI to the DOC (and also likely CBI and the Sheriff's Dept if we include Partridge, Bertram and McAllister in it as well)  The exchange between Smith and Bertram in 6x02 can now be taken as Smith's concern that Jane has information on the Conspiracy, likely due to the death of Brett Partridge.
In terms of a Red John connection to the conspiracy we can infer that Red John is likely a part of it, but the fact that he IS Red John is likely unknown to most of the others.  In fact Red John could have easily been one of the founding members.
Overall, I think that Ray Haffner is now (and for me he has been for  a while) the Prime Suspect in the hunt for Red John.  Looking at everything we have found out I can't see it being anybody else, apart from Thomas McAllister and I think it turning out to be him would be on a par with the old Murder Mystery cliche of "the butler did it" seeing as he appeared in one episode nearly SIX years ago and the writers had no way of knowing whether Xander Berkeley would even want to come back to the show.
Also; Much Props to Baki Kaan Sert for the discovery of the similarities between Red John's and Ray Haffner's walks, which to me simply adds more credence to Ray Haffner being Red John.  The GIFS showing this are here: http://i.imgflip.com/4a7bq.gif and http://i.imgflip.com/4a7e2.gif
