I agree and disagree with both in equal measures:
a) The CPS should definitley have taken the case to prosecution, there was enough evidence at that time (we didn't have the benefit of new evidence at this point and they can only go on what they've got) and regardless of whether or not a rape has been reported, that doesn't mean a rape didn't occur. Also you only have to read the news nearly every day to see that as a society we have a problem with the sexual exploitation of woman from men in power, if you don't like this then it's likely you're part of the problem, imo.
b) In the end the justice system found Ched not guitly. You may not like what he did that night regardless of whether it was illegal or not, but I can guarantee you unsavoury practices like this are far more common than you think, not just in football. Most footballers aren't morally upstanding citizens, they're bored kids who get paid too much and can't go out in public without people worshipping the ground they walk on, it's a weird existence and some are bound to make bad decisions along the way. Even if he was found guilty and had served his time I would be of the opinion that he deserves the opportunity to be rehabilitated and has every right to go and do what he trained all those years to do, that's what the justice system is for. The fact that he was found not guilty to me makes it a big miscarriage of justice, no matter how unsavoury it was, the chap has had his life turned upside down for what in the end turned out to be something he hasn't done. Now he has to live with that forever, everyone who knows him, whether through his fame or personally will always judge him in a way me or you will never have to deal with and he shouldn't either. I feel terribly sorry for him if I'm honest.
Of course that's just my opinion though.
