It's a no from me. I appreciate others are saying that ex-cons need to earn a living. I accept that, but their living doesn't have to be in a job that is so much in the public eye. Think of other jobs that have a similar level of media scrutiny: politicians, TV presenters, pop stars etc. There are numerous examples of people in those positions that after a conviction of a serious crime had to look for an alternative career. Football is similar in that way.
For all the talk that football is only about winning, really they are about more than that. Football clubs should also be positive representation of their community. You couldn't really have much worse a role model than a convicted rapist, so I wouldn't want City to employ one, no matter how talented.
