So the whole bugging the CBI thing bothered me, but now I have a theory.  Remember the scene in episode 2 when Reede Smith asked Jane, "What mistake did he make?"  Jane responds, "I would tell you but I always had a suspicion this room is bugged... wired."  He kind of does a quick hand movement while saying so.  

This might be a stretch, but maybe Jane hypnotized either Red John or one of his accomplices to bug the CBI, which he knew would be kind of sloppy and possibly lure Red John out.

Just a thought.
