In my opinion, NO! Prisoners are not part of our society. Here’s the thing; they are behind bars, away from general population simply because they have committed a crime and therefore are dangerous to our society. From murderers to rapists to thieves and alike, prison keeps them all in check and in the process, make the country safer to live in for us. When you break the law, you have no business enjoying the rights that would otherwise have been at your disposal had the crime not been committed.
For me anybody that breaks the law doesn’t have the country’s best interests at heart. Yes, people do change, and usually when someone shows an improvement in their behaviour, their sentence is sometimes reduced or released when their sentence is done with, crime has been paid full by prison time then, Yes. They can vote then.
Letting prisoners vote is taking the value out of our country and the law that built it. I am not in any way saying that prisoners are all necessarily evil but when behind bars and found guilty of charge by our justice system, they are not part of the citizens that can demand full rights.
People need to understand that there are consequences to committing a crime. And having rights denied is one part of it, selecting wisely on who leads the country.
Conclusion: Prisons are for separation and rehabilitation, not pampering them with rights. If they failed with their own life choices that made them end up in prison, what makes you think they are capable of selecting and voting who is the best candidate to run our country?
