Well, we also have to consider that maybe someone does live with this guy, and can't shake the feeling that somehow he is BG. Then they also have to consider being wrong, and they probably love this person, and still cannot fathom that they are living with a monster. Then comes the fear. Even if they call in a tip, and maybe know where evidence is hidden,it may take LE awhile to follow up, and even longer to make an arrest. If he's capable of killing children, why wouldn't he be just as quick to kill a girlfriend, wife, brother, etc? It's much easier to think we would know how we would act in that situation than to actually be in it. As bad as it sounds, whoever BG is, there are undoubtedly people who absolutely love him, and would never want to accept what he is, even if they suspect it. It's just human nature. IMO
