You are forgetting what the question was...

Christ, we're going around in circles here. Maybe if I use all caps you will better understand me. HE PLEADED THE FIFTH ON EVERY QUESTION. If Uelmen had asked him if he killed Kennedy, he would STILL have taken the fifth. It means absolutely nothing unless it was the only question that he refused to answer, which it wasn't. It's really, really simple mate.

Fuhrman is the one who used the n word liberally and gloated about violence against minorities

It's completely unrelated to the Simpson trial though. It would only be relevant if Fuhrman said it during the investigation, which he clearly didn't. Those tapes were from 8 years prior to the case. The single biggest factor why Simpson got off is because the defence made the case into a race trial, and the predominantly black jury (10 from 12 with only one white juror) were suckered in by it. That doesn't make them right.

And for your third question, no silly, the dog probably wasn't in the car, but the police did come in contact with it, thus allowing potential blood transfer.

Several other officers observed blood stains both inside and outside the Bronco while it was still locked, so there was definitely blood in there before Fuhrman had a chance to plant anything. Besides, Simpson himself admitted that he bled in the Bronco and at his house on the night of the murders during his police interview the next day. In fact, OJ initially claimed that he could not recall how or when he had been injured, but later said that he cut it while retrieving his cell phone from his car while rushing to catch his flight to Chicago, literally minutes after the murders took place. In other words, OJ effectively admitted to badly cutting his hand within the same hour that his ex-wife and her friend were stabbed to death. Boy, these "coincidences" are really beginning to stack up now, aren't they?
