after watching the "new episode" i have come to a new theory
THERE IS NO RED JOHN.
in all of the seasons we can see alot of characters are involved some way or another with "Red John",some are friends of "him" and some are "Working" patrick in order to trick him and gather time for the real "red john" to escape.
What if there is no red john?
and red john is a code name for patricks "case" in the Tiger Tiger organization?
How do they recruit members?
maybe in order to get the 3 dots and to become a part of the "Tiger Tiger" they need to go via some kind of "Test" or show dedication
toward "Tiger Tiger"?

so the theory is.
EVERY ONE IS RED JOHN.
every person in tiger tiger commited a crime in the name of "Red John" in order to misslead patrick and in order to keep Tiger Tiger a full working organization?

FELL free to bash it.
thats what fun about all of this! :)
