re: In your opinion, did OJ kill Brown and Goldman?

As a soon-to-be law student, I'll use my still limited legal knowledge, and say that I blame the prosecution's failure on two things (other than racial views within the jury):

1) The glove. Chris Darden should have never asked him to try on the gloves. The problem was that due to the blood soaking the gloves, they had drawn up; the gloves had been kept cold to preserve evidence (cold wasn't good for the leather); OJ had to wear latex gloves to avoid harming the evidence on the gloves. These factors made it likely that the gloves would have had no chance of fitting, and the prosecution should have known this. I think Darden thought the gloves could be their big moment, but it back fired.

2) Putting Mark Fuhrman on the stand. The defense employed a racism narrative to raise the possibility that Fuhrman (who found the glove at OJ's house) had planted the glove there and thus, raise reasonable doubt. Fuhrman then testified that he never used the "N word", which was debunked by the tapes of him saying that word. This worked out perfectly for the defense, as it made it clear that Fuhrman was a racist and helped the narrative that he could have planted the glove because of racist motivations.

However, Lead Prosecutor, Marcia Clark, has since raised a good point which is that she had no choice but to put him on the stand. Because he found the glove that was at OJ's house, having other investigators testify instead of him would have raised suspicion that the prosecution was hiding something.
