Just a thought.I know most of you believe that Sheriff Thomas McCallister isnt RJ and if he is it will be dissapointing.Anyway i dont know if he is RJ indeed but im pretty sure that he isnt just a Sheriff.If you pay attention in the conversation between him and Van Pelt at s01e02 especially when he says "I think you are drunk Mrs" you will see a man that tries to seduce Van Pelt(i dont know the reason and thats the key).I dont know if eventually McCallister will be RJ but the fact that he is on the list isnt random at all.
