At one time I used to be a supporter of the death penalty for the following reasons. I thought that it acted as a deterrent, that it made them pay the price of their crime, it showed the general public that justice was being done, and that it gave closure to the relatives of the murder victim to see the killer being executed.
Now lets examine those points. The death penalty isn't a deterrent, as the American states that kill murderers have a higher murder rate than those states without the death penalty. It doesn't make them pay for their crime and only acts as retribution, which has no place in a civilised society. It doesn't really show the general public that justice is being done, only that the state knows how to kill. Killing the killer won't give the murder victim's relatives closure, only leave an empty space in their lives.
Nowadays I am opposed to the use of the death penalty. If the state executes a murderer, this then makes the state a killer as they are killing to prove that killing is wrong. This makes the state a hypocrite. Also, the American use of the death penalty violates the 8th Amendment of the U.S. Constitution which outlaws the use of any cruel or unusual punishment. The gas chamber is a gruesome and painful way to execute someone, described by doctors as dying with the feeling of suffocating, intense muscle cramp and having a heart attack all at the same time. The electric chair causes severe burning, and even the lethal injection isn't pain free if it's not carried out properly. The biggest problem with the death penalty is that if you execute someone and it turns out afterwards that they are innocent, then it's too late to do anything about it. Even with DNA evidence, mistakes can be made and some of the evidence can be falsified.
I think that the answer to regaining public confidence is to give longer tariffs (the minimum amount of time that must be served on life sentences). At the minute, the starting point for setting a tariff on a life sentence for murder is 15, with it being increased or decreased accordingly to take in to acount any aggravting or mitigating circumstances. If the starting point for setting tariffs was 25 years, then this would give the public more confidence in the criminal justice system, and less likely to call for the death penalty.
