The case of the man who murdered a boy in front of his sister, videotaped it and made the little girl burn her brothers body -
execution.
This girl in Monroe who was buried alive?
They find who did it - execution.
Yes, there are going to be occasional punishments dealt that were errors. As long as there is a human element, there is going to be error. All we can do is constantly strive to ensure that the lowest margin of error exists. It is unfortunate and tragic when an innocent man is convicted but that is no reason to allow hundreds to walk free.
Mind you, the cases I mentioned are all extreme cases of child rape/murder/molestation. In those cases, which I see as being the most horrible crimes a human being is able to commit - there is no extreme undeserved.
