The Soviets intentionally used short drop on their Nazi war criminals.
That presupposes they
could have performed a long drop hanging ...
Pierrepoint isn't a very reliable witness in some areas (I mean there's something deeply unsettling about his admission he had a "special" leather strap for "special" victims). However some of his facts seem to hold water.
He was very critical of the US need to have the condemned standing on the gallows for ages while the charges were read. And if you are going to have capital punishment, it's hard to imagine a more humane way than the 8 seconds from door to drop that he had mastered.
Ultimately the problem with capital punishment is that unless you are going to boldly state you have a perfect criminal justice system. That is 100% perfect with no mistakes ever. Then you are basically admitting you are going to kill the wrong person sometime soon. Simple as that. No ifs. No buts. You will kill someone innocent.
Not in my name.
And having killed the wrong person, the system will do all in it's power to avoid admitting it - even if that means a murderer remains free. Because police are hardly going to go looking for "The Malvern Murderer" again after they are supposed to have caught and executed them are they ?
