I think I mentioned this before, behaviour, the reasons why your in prison, and the length of your sentence should determine whether you vote or not - Ian Huntely does not deserve any voting rights, because he might be dead before he gets out, and someone as sick and evil as him shouldn't have any say in what happens in our society.
If voting is conditional, for whatever reason, then what about people who avoid taxes, people who hold extreme views, the terminally ill, people with suicidal tendencies. What about arms dealers and crooked business men who don't get put inside? Does being convicted and fined mean you have your voting rights taken away? It's the same old Daily Mail Daily, Express, James Whale garbage about prisoners = rapist and murderers. And who decides who has the right in your system? A phone poll on GMTV? Or a panel of judges with vast experience in the law..... oh sorry that's what just happened isn't it?
What is the problem with Ian Huntley voting exactly? Is he going to vote for the "Murdering Little Girls" party? If you believe that he is a man so far from the normal values of society, then what is the likelihood that his vote would tip the balance one way or the other, so what's the point? Members of the BNP can vote and stand for parliament, aren't they sick and evil?
