I know the people behind these documentary's have an agenda so I am not completely suckered into there bias, however I have seen too many examples of the crazy US justice system failing to ignore them. It's hard for the vast majority of people to contemplate committing a murder, it's equally as hard to contemplate giving a false confession, however in a number of these cases it is clear that there were horrendous tactics, lies and oversights by the police and prosecutors who are all incentivized to get cases closed as quickly as possible, seemingly without caring if they are putting people in jail for most of, if not all of there lives without doing the actual investigation. It seems like once they have you locked into their target, it doesnt matter what actually happened you are going down...... Which to me is as scary as some of the crimes committed. There are some bad people in the world that do unthinkable things, which have been aloud to continue doing them because of the arrogance and corrupted nature of some law enforcement.
