The problem was that the niggersayer cop was a real piece of shit, an obnoxious and morally (at least) corrupt LAPD pig who had a history of running his mouth and otherwise being dishonest. Additionally, there were some questions about the evidence, especially the infamous glove, that were greatly exacerbated by that particular cop forcing his way onto the scene (he literally went out of his way to put himself there and also played real loose with the initial search including mishandling evidence).
It's difficult to say that OJ would have been convicted if that cop wasn't involved, as the timeline and evidence were both less than clear (OJ driving home and cleaning himself up from a blood-soaked murder scene in a span of under an hour, only a few drops of blood in the Bronco he drove and his home etc.) but it would have made the prosecution's case easier.
I recently read a breakdown of the case by some hotshot gook lawyer and my takeaway was that OJ was definitely involved in the murder somehow but there was a lot more to it that never came out, possibly a murder-for-hire angle involving gang members/criminals OJ was friends with, as well as a probable drug connection.
Looking forward to fresh riots over Chauvin not getting crucified. Here's the thing - these hominids and hominoids rioted extensively last year and very little came of it in terms of punishment. Why wouldn't they riot again and again? Not only are they not getting punished, but they have an entire sector of government and most of the media running interference for them. Anarcho-tyranny is a blast, ain't it? Welcome to the 21st century, my American friends (and APC).
