Me? Personally? I take a more sadistic stand on the whole "prisoner" issue than most others. No one has the right to rape, murder or steal from, another being. I believe that anyone convicted of a crime where there was overwhelming should be tortured to death. And I do mean literally tortured until they cease to live. Why? Because unless we grow a spine, people are always going to commit crimes. Do you think people really care all that much if they go to jail? Nope. Otherwise they would not continuously commit crimes.
But if they know the only thing waiting for them in these places is a slow, painful agonizing death than they're less likely to commit a crime. Sure, it might be "wrong" but what's wrong to one person may be right to another. And personally, considering some of the crimes that these vile creatures have committed, they deserve nothing less. I do not remember what country it was but stealing? Yeah, you get your hand(s) lopped off. And I find that to be fair and just punishment for that crime.
I can understand why a lot (if not everyone) would be against such a thing because of people who are sometimes wrongfully accused of committing a crime. That is why I said the evidence needs to be overwhelming. Not only that but if the criminal sits there and acts like a statue, there is a good chance he is guilty regardless of evidence and deserves to be punished. I am quite sick of hearing women and children being raped, people being murdered, etc.
If I had a surefire way of knowing whether a person was guilty or not, I would become dish out my own special brand of "justice".
