The club has to consider many factors though so even if they accept he didn't do it, they still have to consider the teams, fans, sponsors, broadcasters, Greenwood and others in all this.
Whatever decision they made would have split everyone of those so no, I don't think it's a cover up or a poor decision.
For many, I don't think there would have been anything, even if it had gone to court, that would have changed the opinion they made immediately when the news broke. I was more open minded, not willing to convict but also not ready to defend him to the death.
