First of all, sorry for my english, I'm not a native english speaker.

Second, here are my 8 points to demostrate that Wayne Rigsby is Red John.

1) Red John should be in front of us all the time. It's not funny if not.
2) Jane killed a fake Red John once, why not twice?
3) Gale Bertram said he called Jane because someone told him to do it. What if Red John told McAllister to do what he did?
4) Red John is a genius, Wayne Rigsby looks like a fool during all the six seasons, nobody could even imagine that he is the real psycho killer.
5) Heller has created a lot of incredible puzzles and event changes during the six seasons, why he could reveal Red John just in that way?
6) They spent six seasons to reveal us the real Red John, why they would do it now, and not in the last episode?
7) This story must end with the killing of Red John, there's nothing after that, right?
8) The look of Red John revealed by the blind woman on a last season (I don't remember in which exactly chapter was that) is pretty much like Rigsby than McAllister. The age, the tall, etc.

Thank you :)
