The police did not murder the woman. They had no motive to do it and they probably didn't even know she was on the property. There's no reason they'd kill her, not without going waaaaaayyy down a conspiracy rabbit hole. It's far-fetched to believe police intentionally frame people for crimes... But what is possible - maybe even likely - is that they find "their guy" and then build a case around that person's guilt, reasonable or not. As I mentioned earlier, if you're right 99% of the time - and police generally are because criminals are pretty stupid and obvious - how do you stay vigilant and identify the 1% of the time you're wrong? That's what the police did to Avery in 1985. It's not that police are corrupt - a few are but most aren't - it's that when you're right so often and do whatever it takes to get "your man", it's hard to step back from the situation and spot the small percentage of times when you're wrong. And if the suspect is poor and/or stupid, the legal system doesn't do enough to defend that person against a police force and prosecution that is determined to convict. I don't believe most of the actions in this documentary are borne out of malice, I think most of the problems stem from intellectual laziness. The cops do this kind of **** all the time but the overwhelming majority of the time, they're right. They get the right guy. So what can we do to protect people when they're wrong? How do we implement stronger checks and balances in the system? That's the real lesson to be learned here, IMO.
