The main reason he got off is mostly because of Mark Fuhrman, in my opinion....
"Mark Fuhrman (born February 5, 1952) is a former
detective of the
Los Angeles Police Department (LAPD). He is primarily known for his part in the investigation of the 1994 murders of
Nicole Brown Simpson and
Ron Goldman in the
O. J. Simpson murder case.
In 1995, Fuhrman was called to testify regarding his discovery of evidence in the Simpson case, including a bloody glove recovered at Simpson's estate. During the trial, witnesses claimed that during the 1980s, Fuhrman frequently described
African Americans with a racist epithet, claims he denied. In response, Simpson's defense team produced
recorded interviews with Fuhrman and witnesses proved that he had repeatedly used racist language during those interviews.
[2] As a result, the defense claimed that Fuhrman had committed
perjury and was not a credible witness.
The credibility of the prosecution has been cited as one reason Simpson was acquitted.[3] The defense claimed that Fuhrman planted key evidence as part of a racially motivated plot against Simpson. When asked under oath (with the jury not present), Fuhrman declined to answer all questions, invoking his Fifth Amendment right. These questions included whether he planted or manufactured evidence."
Once you have a cop that's lied as one of your star witnesses, it's all over.
We had a local triple murder here back in the 80's. My wife babysat one of the victims in the 70s. The alleged murder was tried three times. After the 3rd mistrial and before the 4th trial, it came out that the lead investigator was caught lying in other cases. Once his credibility was toast, so was every case he'd ever been involved with and there never was a 4th trial. And they had to go back and review many cases that the lead investigator was involved with. He was fired. Some cases overturned. Sad all the way around.
