I dont know who red john is. Some points though:
If red john is in the list, then its natural for Bruno to say that we can trust it.
If red john isn't on the list, again Bruno has to lie. He can't kill the suspense, he can't say: 'guys, I'll surprise you'.
POINT 1: So, Bruno saying that we can trust the list means NOTHING.
This is a mystery and drama series. Red john CANNOT be obvious AND he cant be RANDOM (with the exception that he is so random, that was totally unexpected - like RJ being rosalinda harker). The only way that I would be satisfied by who red john is, is that he is either a part of the team, or someone who is connected to PJ via blood relation or other strong emotional connection. This, in my mind, rules out Ray Haffner (random guy), Sheriff (random guy), Brett Stiles (obvious), Reede Smith (totally random guy), Gale Bertram (obvious). There is a distant possibility someone of them is red john, but a strong back story connecting them to PJ is needed.
From what I've seen till now, RJ is not on the list, regardless what the writer says. (has to say). I tend to like theories that include unknown brothers, mystic fathers, team members or totally unexpected person.
