Hi!
So I've been watching this too, I'm on episode 4. Some things really stand out to me about the corruption theory.
The Dassey interrogation was very hard to watch. I think they really did some leading to get him to agree to some of the things they believed happened. I know the body was found burned in a pit used for a bon fire. But could they tell she was shot in the head, her throat cut and sexually assaulted from the ME report? I mean did they go in there knowing her cause of death before Dassey agreed with the injuries? I'm trying to figure out if he actually gave any new information as opposed to just agreeing with the LE officers. Also, the bon fire the night of her disappearance. Any one who was involved in a conspiracy to frame SA must have known about that fire pit and its use. So someone who resides on the property sure would know but.. was SA under surveilience by LE? That could go a long way towards knowing what were the comings and goings on of the Avery family. Lastly the delay in finding the key with his dna on it really gets under my skin. The Dassey confession there was a point made about how SA was very sweaty when he answered the door (sweat was found on the key, to sort of drive that point home).
