He was indeed, having served half of the sentence.
On release, he had two options. He could get on with his life as best he could, being known as a convicted rapist, or he could open a huge can of worms, and appeal. He choose to appeal, and his conviction was quashed as unsafe. The judge, not the CPS, ordered a re-trial.
Once the second trial is over, then we will know whether or not he was guilty of rape.
Only one question you need to ask yourself; a guilty man, knowing he was guilty, and knowing that any subsequent re-trial was highly likely to find him so, would that man appeal? Knowing that if he had not appealed, the matter would gradually be forgotten, whereas the appeal has put him on the front pages again.
It is of course possible that Evan's hubris is of such a level, that he feels that because he says it, it is so. I doubt that though.
Time will tell, as always.
