Without a doubt, the cops coerced Brendan into saying what they wanted him to say. Every time he said something they replied with "you're lying, Brendan, what really happened?" "We know there's more, tell us about the gun," etc. Dont you think he would have mentioned something about shooting Theresa the first 15 times he told the story? The cops had this story fabricated, and they steered someone who was completely vulnerable into saying what they wanted to hear. Brendan has the intelligence of what, a 5, 6 year old? If I went to my niece and used the same tactics, and promising her that everything would be okay (as the police did to Brendan), then I could get her to admit to anything as well.
I also think it is convenient that the whole story that was fabricated to pin down Brendan was essentially thrown out the window for Steven's trial. It's like they were sentenced for two completly different acts.
As far as my opinion, I believe they are innocent. That doesn't make Steven a better person, because he is still a sketchy person, but he is not a murderer, nor is he a genius, which is what he would have to be to do this murder as he was convicted of doing it (shooting her in his garage, or even slitting her throat in the bedroom) without leaving ANY sort of evidence behind. Come on. Even in the slightest chance that he is guilty, the way Manitowoc County handled this case, everything from the investigation to the trial, I don't think he should be in jail. Everything about it was handled like a preschool treasure hunt. There are so many loose ends, and even if you believe the prosecution evidence that was left out of the documentary was damning, the defense evidence left out was even more compelling, in my opinion. Will all of that, there is no way there is enough evidence and lack of reasonable doubt to keep Avery and Brendan behind bars. Give them a fair trail, which I realize is impossible now, when no one wants to admit they fucked up so bad when there are dozens of "good American citizens" whose lives and reputations would be at stake in the fallout.
Also: Fuck Ken Kratz. He's Vernon Dursley's shithead brother.
