I make it a rule to NOT read comments sections. As a rule, that is where the least informed and most opinionated people hang out.
And let's be honest here. Nothing the Chicago PD has to say about 20 years ago should be accepted as fact. They routinely tortured people into confessions for crimes they didn't commit in order to close cases, and in some times to cover their own crimes, even keeping a secret interrogation center off of the books that the used to beat subjects into submission. The City of Chicago has paid out over nine figures in lawsuits and settlements to pay off victims of these crimes. People like Jon Burge wrote confessions for victims and fed them to them, so his "knowing" details of the crime while being innocent isn't even that implausible.
Finally there is zero physical evidence connecting him or the other man convicted of this crime. At this point, this is Donald Trump saying that the Central Park 5 are still guilty, even after they have been full exonerated.
