according to the courts of Cuba he is. Hence he's not innocent. But just like with OJ there are plenty of people who have the opinion he innocent too and believe it's a fact that he not guilty of anything.
Who cares what the courts of Cuba says or does? I don't place any stock in what some kangaroo court does in a dictatorship. And just because someone is convicted doesn't mean they are actually guilty. Just like someone who is acquitted isn't necessarily innocent.
It's not a fact that OJ isn't guilty of anything. It's a fact that he was acquitted during his criminal trial. But anyone who followed that trial and has a half a brain knows he was guilty as sin. Plus he was found liable in civil trial on the same subject matter.
