Factual error: Joe's plan to trick OJ into confessing to the 1994 murders is moot since, having been acquitted, the double jeopardy provision would prevent him from being tried for the same crime twice, and as a cop, Joe would know that.
Suggested correction: The plan to get OJ to confess had nothing to do with getting the confession, so he could be arrested or tried again. And at this point, the civil trial already found OJ "responsible" for the murders. Since OJ has always maintained his innocence, getting a confession on tape would just be big news.
