First and foremost,  I
honestly have no clue who Red John is. 
There have been so many clues; however, most of them are subject to
various interpretations.  I prefer to
stay away from all of these clues because I don’t want to speculate on
something that could go multiple different ways.  Reading many of the theories on this site,
many people aren’t convinced of certain things. 
For example, is Partridge really dead? 
Do we trust the info on the psychiatrist’s recorder about Red John?  Is McAllister crossed off of the list of
suspects?  Is Red John a group of people
or just one person?

So, if we are to assume that Heller is being straight with
us about this list of 7 suspects, then that is really the only true fact that we
have.  The rest is interpretation and
speculation based on interpreted information that could have been easily
misinterpreted or purposely planted by Red John to mislead.

The one thing that has bothered me throughout the entire
show is the fact that Red John is always one step ahead of Jane and everyone
and everything for that matter.  Some of
RJ’s knowledge and actions seem almost impossible for him to know or do unless
he is some type of omnipotent being.  This
is what has troubled me the most.  So
this has led me to believe that RJ must have accomplices or that RJ is a group
of people.  However, I struggle with this
concept because the more people that know about something, the harder it is to
keep it a secret and maintain control.  Ben
Franklin said it best… “Three can keep a secret if two are dead.”

Now some new light has been shed on this Tiger, Tiger
concept.  This might help explain things
somewhat, but now I am speculating. 
Tiger, Tiger appears to be some sort of secret group within law
enforcement.  Perhaps it is a ring of
officials/politicians/cops/etc that will do bad things in the name of justice (planting
evidence and including killing others to keep their secret).  Or maybe they are just corrupt through and
through… though I don’t think so. 
Regardless, the Tiger, Tiger group could be how Red John is able to know
so much and accomplish so much.  Either
they work directly for Red John and know Red John, or it’s the opposite…  I think they have no idea who Red John is, but
Red John knows everything about them.  As
a result, perhaps Red John is able to manipulate certain information and even
manipulate certain actions from the Tiger, Tiger group.

He may even be a part of the Tiger, Tiger group.

This helps explain my dilemma that I have struggled with throughout
the entire series.  Red John is Red John
(not a group of people) and therefore, his identity is more easily concealed.  However, Red John is somehow able to
manipulate the Tiger, Tiger group into obtaining information and performing
certain actions on his behalf without them knowing it.  Because the Tiger, Tiger group does its own
illegal activities, this makes it easier for RJ to manipulate the group.  This explains how he is always one step
ahead.

Or perhaps Red John is a red herring.  A serial killer was invented by the Tiger,
Tiger group to cover up the elimination of certain people that they wanted dead
for whatever reason.  Though, I hope this
is not the case, and it does not make sense. 
If this were true, then Jane’s family would still be alive.  They were killed because Jane called Red John
out.  If Red John were a group of people,
the group would not have cared about this or taken it personal.

Why was Kirkland killed? 
What purpose did it serve?  I
presume the answer to this is simple… He knew about the Tiger, Tiger group and
therefore he knew too much and had to be eliminated.  I can’t think of any other purpose that would
have been served for them killing him.

One other thing that is bothering me.  At the end of season 5, RJ tells Jane he is
going to start killing again and with more frequency.  Assuming RJ is who killed Partridge… then why
did he specifically kill Partridge and where is this alleged increased
bodycount?
