A great documentary expose that is appalling and scary - or ought to be

Every moment of the Demos Ricciardi Netflix documentary, Making a Murderer, kept us focused and "glued to the screen" and eager to get the next bit of info - right to the end when we, like most viewers probably, went online to get even more info. Obvious many spoilers here so just watch the 10-part series if you haven't done so yet. Otherwise: yes, a few things are obvious. Brendan was totally screwed, first by the police with the illegal interrogation, then by his so-called defense lawyers who pushed him to confess so as to make him a valuable witness, finally by the court system with its perfunctory review, much of the review by the judge who ruled in the first place. He should be free, without question. Steve Avery is a tougher call. I am not sure he's innocent, but I don't have to be sure. I am sure he was also screwed by investigators and prosecutors and a biased judge - all of the lower-court system are in bed with one another and far more likely to give credence to the word of a cop or sheriff and certainly not to a sketchy outsider oddball like Steven. Still, it's very possible he did commit the crime, though there's still plenty of doubt, at least as far as the documentary shows. Though there are many doubts about Steve - no blood in the bedroom after the rape and murder?, no sign of the manacles or rope holding her to the bed?, no sense of the timeline?, - nobody even tried to make a plausible case for another perpetrator. Reading online afterward it may be there there was prosecution evidence that was in the trial but not in the movie, e.g., a series of calls from Steven to the victim, manacles or handcuffs in the so-called burn pit - these would cast further suspicion on Steve, so omitting it in the documentary was smart insofar as this is a polemical piece but a serious compromise regarding the full picture. Several points that were raised in the film need some elucidation, too: who was making annoying calls to Theresa? What did that investigator mean when describing the Avery family as satanic? I'm sure there will be a lot more about this film, but, even in Steve is guilty, the depiction of the trial and the consistent violation of his right to presumption of innocence is appalling and scary (or ought to be). The come-uppance for the sanctimonious prosecutor, though not necessarily relevant to this trial, was final fillip on a great documentary expose.
