What if the DNA test got screwed up? It happens. What if the police were corrupt and planted DNA evidence because they believe, without proof, and maybe incorrectly, that a person is guilty and they don't want to see him/her walk? It happens. What if DNA is at the scene of a crime, but
isn't the DNA of a murderer? It happens.
Like I said - nothing is clear cut and crystal sharp, everything has 'what ifs'. Yes, of course there will always be some cases where there is 100% absolutely no doubt, but the problem is, if you allow the death penalty for those, where do you draw the line that says 'this is what has no doubt, and everything else isn't.' Because if you can execute someone because he kidnapped, locked up and abused someone for 18 years, do you also execute someone who did the same thing for 10 years? How about someone who kidnapped and raped an 11 year old girl and then let her go? Is it the rape, or the kidnap, or the time? And how do you extrapolate to another crime? Or look at it the other way - someone kidnaps and rapes a series of young girls, but is careful and leaves little or no evidence. Eventually this person gets caught, but won't admit to the crime. How much evidence do you need to execute them? Do you need DNA? What if there is no DNA evidence, but, say, four out of six girls positively identify the person? Is that enough to execute them? What if some of the girls were murdered as well as raped, is that enough, even if there is still no DNA evidence? What is enough?
Where do you draw the line? Because the moment you have the death penalty, that's what you have to do, draw a line, and any line we draw as fallible, emotional, empathetic and feeling human beings, is going to be crossed the wrong way; the guilty will not get that punishment you think they deserve, and some innocent people will.
In the end, though, no argument on-line is going to change the opinion of a single person posting here, so I'm going to respectfully agree to disagree, and go play some good music.
Edit - btw, it's why
America has a death penalty.
We don't, those of us who live in Australia, New Zealand, the UK and Canada. Just saying.
Why treat life as a journey to the grave with the intention of arriving in an attractive & well-preserved body? Get there by skidding in sideways, a glass of wine in one hand, chocolate in the other, body totally worn out, screaming WOOHOO! What a ride!
