Ahhh, but he wasn't found to be innocent. He was found to be "not guilty", meaning legally he was free, but losing the civil case was the true indicator.
And hasn't that been his entire problem? He thought, whew, this is over, back to my glamorous lifestyle... wrong.
No one that he wanted to be around, wanted to be around OJ after that. His phone stopped ringing almost immediately. If it did ring, it was from someone that 5 years earlier, OJ wouldn't have given them the time of day.
Now that's irony and poetic justice.
