It raises the question, which jobs can convicted rapists have and which can they not have?
Doctors, teachers, social workers, police officers... these are obvious examples. Obvious because access to vulnerable people is part of the job.
But professional footballer? All that necessarily entails is playing football.
I'm aware that many footballers spend time on local community projects or fan meet & greets at the behest of the club or sponsors... but it's conceivable to imagine someone playing professional football whilst not being required to do those things. So the argument of 'as a footballer he'll be around vulnerable people' can be mitigated IMO.
The other objections are a little absurd and knee-jerk for me. Commenting on the high salary of a footballer, for example. Are we to set a salary limit for convicts? Should they also be excluded from being bankers, or running a successful business? It's just not workable.
The argument regarding footballers being role models and therefore he should not play, seems off to me too. It's not a necessary component of being a footballer, and in fact is imposed on a player by those who hold them are role models. It seems strange to me that society promotes footballers as role models anyway when my general impression of them is that they are unfaithful, womanising, entitled morons who earn silly amounts of money for shepherding a piece of leather into an outdoor cupboard.
Anyways, rapists have to work somewhere. I don't want them sponging off the state for the rest of their lives. Also, it's a principle of our justice system that once you've done your time, you're free to go and get on with your life. The principles of our justice system are more important than emotions surrounding a highly publicised case.
