In this case, the police themselves reported the nature of the crime and confirmed what he was arrested for.
That feels highly unethical and utterly unfair on the the person they've apprehended.
Putting out a press release that charges were dropped if it turns he didn't do it is the equivalent of a newspaper printing false information about a person on their front page and then printing a retraction in a tiny corner buried at the bottom of page 29. The cats out of the bag, the damage has been done, no-one is going to remember or care about the retraction after the initial front page headline has taken on a life of it's own.
Obvs it goes without saying, if he is found guilty then throw the book at the lad and I hope Chelsea rips up his contract, but until such a time, we will have to assume he is innocent.
