DId anyone else notice a black car rushing away from the scene as soon as the police arrives at the bomb site? I think it was the real red john escaping from the place as Rigsby says in the S06 E07 promo that the real red john has thrown a bomb at the place trying to kill the suspects and PJ

A few things to point out, 

First of all, that twin brother of Bob Kirkland is not RJ, we have never seen him, we haven't received any clues that point in his direction. It would be completely lame if he is RJ, which of course he isn't. 

Second, also stop thinking about Rigsby, Cho, Van Pelt and Teresa. This would also be completely lame, there are no clues leading in their direction and Patrick would have figured it out years ago. 

Thirdly, please read the theory below. I have read quit a few theories, but this is most definitely one of the best. It explains why Brett Patridge is RJ, and I agree completely. 

Certainly worth reading!

Finally, 
I just wanna say that it would be wonderful if RJ is a character in the show that we've seen for the first time in (one of) the first episode(s), and just went along with the show. He comes and goes, we don't recieve a lot of clues about him, but there is always something weird about 'that guy' and Patrick knows it aswell, but he just couldn't be sure. 

Brett Patridge is 'that guy', Heller knew from day one that he was RJ. I like it! Love the show.

Thanks for reading,
And sorry for my English. 

i dont think red john is just one person i think red john is everyone with the 3 dots i think red john stands for a cult or some sort of secret orginisation and not just one person

Whoa I think the lady who was feeding the pigeons on the bench in the premiere was at the visualize ceremony!

Pause the episode at 12:08 and you can see her. She has a silver watch or bracelet on. Do you guys think it's her?

i don't have a link to her at the visualize meeting since it's not on the web much yet, but pause it after bret stiles yells "I PROMISE I WILL RETURN!" and it pans to show an applauding crowd. She is there.

Gale Bertram
Reed Smith
Thomas MacAllister

One of them is RedJohn. Bertram is the TOP choice. Especially because of the close mean look he gaves to Patrick. That look means "you got me bastard, I am so going to kill you now".
Enough theories. The stage is set. We finally got him.
