well there was a long history of documented physical abuse of Nicole, and she had told many people that she was afraid he'd kill her someday. there was also a great deal of physical evidence at the crime scene - his DNA was everywhere and he didn't even try to cover his tracks
Well he was broke at this point due to legal fees and fines, so a provocative book makes sense if you want to sell. But it was seized by the victims’ families and he didn’t make anything.
He literally didn't write it, nor title nor release it as is. A court ordered the book rights be handed over, and they then deliberately made it look like a confession.
I mean this is kind of true, but they didn't have the authority to change the contents of the book or the title.
The thing they did to try to make it look like a confession was the graphic design of the cover making the word "If" difficult to see, so that it kind of looks like it's called "I Did It."
I haven't read it so I can't comment on the veracity of shath's comment, but if it is true then it's not because her family changed the text of the book.
EDIT: you know what, looking into it more, it definitely does sound like more was changed than the cover design so I'm just going to say idk what happened here and it could be a significant rewrite, sorry CarbonScored
How can we be sure anyone did anything or was anywhere? Even in cases where there were eye witnesses or DNA evidence, none of that is conclusive in the pure sense, it's just a testimony and occurrence. There's always a possibility that everyone is lying, the video evidence has been tampered with, the fingerprints were planted or perhaps the lab mistakenly identified them as so-and-sos when they were really someone else's. All we can do is determine based on the available knowledge and wisdom of the day how likely it was that a crime was committed based on the evidence.
With the case of OJ, there was a pattern of abusive behavior in his relationship with his ex wife, DNA evidence at the crime scene, and the murder itself based on the condition of the bodies of the deceased and the state of the crime scene suggested that the assailant committed an intensely violent act on Nicole and her friend, not characteristic of a botched robbery etc. Along with OJs testimony and his suspiciously timed travel arrangements, and in the absence of another theoretical perpetrator, there is a pretty compelling case against him.
