I understand your feelings on this subject Speel, but everyone's entitled to an opinion.
My own viewpoint is that capital punishment is unjustifiable and flawed. I also believe that there is no "quick and efficient" way of executing someone as botched executions are more commonplace than you think, and that the law must be 100% correct before any permanant action (ie execution, mutilation, castration etc) is carried out.
However, if someone close to me was murdered in cold blood I know that my emotions would be somewhat different and I'd be baying for their blood or their tender parts on the chopping block.
Just trying to bring a little balance here folks...
