I think the reintroduction of capital punishment being considered as an economic solution is a wee bit...dare i say it sick, Obo. As a deterrent, well, have a look at countries that have the death penalty and tell me if it has lowered the murder rate. As for scientific evidence, I don't believe there's such a thing as the perfect justice system. Mistakes are made and yes, believe it or not evidence magically meterialises from time to time in some cases. Foolproof evidence, I believe does not exist and probably never will. There are highly, sophisticated methods of investigation and forensic skills out there, but alas, even these methods are imperfect. How many innocent people do you think are sent to their deaths each year on this planet, I'm willing to bet quite a few. What sort of percentage do you think are guilty? What do you think an acceptable number of innocent deaths is before you can vindicate the use of a death penalty in this so called civilised society?...I really hope you're not thinking of a number. What indeed do you say to the family of an innocent person who was put to death due to an imperfect system?........."oops, sorry"? I'm sure they will great take great consolation in knowing that their loved ones were killed by mistake. I think that it is wrong anyway in a civilised world to legally kill people. I like to believe that human beings are inherently good. I believe that the evil that occurs in this world is due to a social and environmental disease and not explicitly a human one. I think a preventative way of thinking rather than reactionary one would be the best way ahead.
