I do not execution should be used in all murder cases, such as ones where only 1 person was killed or when it was not premeditated. But people that slaughter, and torture their victims with a slow and extremely painful death. The way the United Sates court system works it is not likely an innocent will be executed. Once a person is convicted of murder in states that have the death penalty there is a penalty phase that the prosecution asks for either life imprisonment if they think their is a chance to reform them, or death if the murder is so sick in the head and not reform able. The jury then reviews the evidence, how heinous the murder is, and if they murderer is reform able, then they give the verdict of life or death. While on death row inmates are there for well over a decade, and have all the tools to get a appeal, or if the are innocent to prove their innocence. 12 people would not condemn another human to death if their was any doubt in their mind about their innocence.
