Unless we've managed to raise people from the dead, the death penalty does have a flaw that mistakes can never be rectified.
Spending a substantial amount of time in prison for a crime you didn't commit is also a mistake that can never be rectified. I guess you're one of those people who think that if enough money is given to the wrongfully imprisoned, the mistake is rectified? I would hazard a guess that you'd have a hard time finding someone who would feel that losing a substantial portion of one's life is rectified by money (not even considering what life in prison is actually like).
In addition, once someone is executed, the strongest advocate for their innocent (themselves) is gone, and it's unlikely that others will take the time to prove their innocence.
Who in prison has ever proved themselves innocent?
We have executed innocent people before. We've literally released over a 100 people from death row since the death penalty has been reinstated. We've also executed people and found strong indications that they were innocent only after they were dead.
Sure. And sadly, that kind of effort is almost always put forth only in death penalty cases. Because apparently some people think only people faced with the death penalty deserve that kind of *special* consideration. That's one of the things that I find really troubling about your and Cornsail's position in this discussion.
Can I ask why you are against the death penalty if you believe a life sentence is an equally harsh punishment?
1. Because death penalty cases eat up resources, financial and otherwise, at an astonishing rate.
2. Because to kill someone in cold blood as punishment for killing someone doesn't make any logical sense.
3. Because for a society to take a life in cold blood without any need to is detrimental to that society and the individuals which make up that society.
4. Because carrying out an execution is detrimental to the individuals doing it, and if it doesn't have a negative effect on them, then they are not the kinds of individuals that should be chosen to represent the society.
5. Because I know that I could not carry out an execution in cold blood without that act having a significantly negative effect on who and what I would be from that point forward, and having someone else carry out the execution on my behalf does not lift the responsibility for the act from me (see item #3 above).
I think there is plenty of wiggle room in the interpretation of how much doubt is "reasonable doubt". From my experiences observing and discussing various cases, I have the impression that my standards for "reasonable doubt" are more conservative (i.e. I'm less likely to consider "beyond a reasonable doubt" to have been met) than many other peoples', death penalty case or not.
So what would be achieved by adding a different standard of proof in death penalty cases? (Other than to say, "Hey, if you're just potentially sending someone to prison, for life or for a lesser sentence, it's really not something that you need to take all that seriously.") And what would your standard of proof be?
