Only the first means freedom. Actual innocence doesn't guarantee freedom, and actual guilt doesn't guarantee a loss of freedom. He's either innocent or guilty regardless of any court proceedings and regardless of anyone's opinion. I suspect most of "the authorities" share my well-founded belief that he's guilty, as it's based on facts that have been known to them for decades. I may be wrong, and I may be right. The fact that I believe he's guilty doesn't make him guilty, but the fact that he was released from prison doesn't make him innocent, either.
