I don't think they should be able to vote. I don't really understand the violation of human rights arguement at all.
If you go down that road, surely simply being in prison is a violation of their human rights?
They CHOSE to do a crime - very few are inside for no reason or because they were forced. When they chose to do that crime, they knew of the possible consequences - possible imprisonment - yet they chose to do it anyway.
Prison is supose to be a punishment. It is supposed to take away their freedom to do ordinary day to day stuff. And also took away their right to be a member of society for a while.
Voting is the ultimate part of belonging to a free country I guess. Well, they chose not to be a part of that free society (when they did the crime), therefore they chose to have that right taken away.
I have actually discussed this with a couple of clases of inmates (male, range of crimes, range of ages, crimes from cat C type - drugs, etc - to cat A/lifer - nasty stuff). The majority did not feel they should vote whilst in prison. For many reasons - some apathy to voting anyway, some as they felt that in prison they should have that right.
Makes you wonder if it is just another way of trying to get more people to vote seeing as numbers go down year on year.
