CE continues to protest his innocence. It would be unnatural for someone to apologise for a crime he asserts he didn't commit.
One of the troubling aspects of this is the lack of insight he shows into what happened. The BIG problem with his case is that, on his own evidence, Evans got a text from his friend, Clayton McDonald, to say that he had “got a bird”, neglecting to mention he had “got” her at 3am in the queue for pizza when she was so drunk that she fell over and twisted her ankle. In fact, she had drunk so much that she doesn’t remember how she got to the hotel room where she eventually woke up, her clothes scattered around the floor. Evans says that he got a taxi to the Premier Inn where McDonald had taken the 19 year-old, let himself into the room and “got involved”, while his brother and another friend watched through a window and tried to film it on their phones. He left later that morning via a fire escape. In that sequence of events, based on his own account, he made no effort to think about or find out whether the victim was capable of consenting to anything.
He's had a full trial and two goes at appealing, and each time his guilt has been reaffirmed. He doesn't have any appeal ongoing at the moment, he simply hopes that the CCRC might find more appeal grounds and help him put together another application for leave to appeal. So, if he's prevented from apologising, it is purely because he is clinging on to the very slim hope that the courts will agree with his own perception that he didn't commit a crime.
It is of course his right to do that. But he then has to take the consequences. And, as has been pointed out, he could at least mitigate those consequences by pulling down the website and doing his utmost to stop the victim being hounded. The fact that he has failed to do so speaks volumes and suggests that he doesn't actually have that much belief in the strength of his case.
