I am wondering if you are an American or were even alive during the trial (It's been almost 30 years!!!)
Anyway, to address your points.
#1. You're goddamn right he absolutely got better representation than you would ever get because he's a rich celebrity...
It's financially easier for him to start a new brand than it is for you to go buy a simple art kit or pay for a month's worth of gasoline or any other car fuel or pay carfare.
Well, that is a flaw in our justice system, then, and why we shouldn't have a death penalty at all. If poor people are convicted because they are poor and rich people get off because they are rich, that is an injustice.
Still, OJ didn't get off scot-free. Despite being acquitted, his acting career vanished, and no one would touch him as a spokesperson at that point. He was down to selling memorabilia on the side to make ends meet, which is why he went to jail for assault. The system gets you eventually, if it is out to get you.
(The "robbery" Case against him was kind of bullshit, as all his accomplices who did the violence part were given plea deals and no jail time.)
#2. The N word should not have mattered one iota, his guilt should have.. but money buys everything, including the racism that created the acquittal.
Um, no. With no witnesses, this came down to the forensic evidence, and all that forensic evidence was collected or found by Mark Fuhrman. A guy who liked to collect Nazi memorabilia and whose fellow cops called him "Fuhrer-Man". So his bias was a legitimate issue to mine, and frankly, Darden and Clark fumbled that football.
#3. Depending on the Judge's age and the judge's attitude about life, OJ Simpson might also have more bias-in-favor from the judge too.
Um, there's a lot to be said about how badly Lance Ito handled this trial. The guy fell in love with his press clippings. He let the trial go on too long and down too many rabbit holes.
But I also put a lot of blame on Darden and Clark, who were chosen for their gender and race, respectively, over more experienced prosecutors. They made a LOT of errors in this case. - Not vetting Fuhrman and the othe cops, and of course, the idiotic glove incident.
But at the end of the day, this was only a year after the LA Riots, and a mostly black jury decided to give a middle finger to the LAPD.
