If a jury decides that the prosecution has manufactured evidence against a defendant, are they entitled to find a defendant not guilty, even if they think that the defendant committed the crime they were accused of?
If they did decide to do that, would that be considered a case of jury nullification?
If they are not entitled to do so, what deterrents are there against the prosecution manufacturing evidence against defendants?
I'm thinking about this because of the OJ Simpson case, where I've heard that he did commit the crimes, but I've also heard that the prosecution manufactured evidence.
Los Angeles Police Detective Mark Fuhrman subsequently faced charges of perjury because of the OJ Simpson case, but the jury would not have known whether he'd face such charges when they handed down their verdict.
