As capital punishment has been mooted a few times in this thread, I would like to say that I believe it to be barbaric, and I'm very glad it's no longer a punishment here in UK. I've just finished reading an extremely interesting biography of James Berry, Executioner in UK during the latter part of the 19th Century. He noted and described many hangings he performed, (and they were not all the quick, painless affairs one might imagine.) How any human being could snuff out the life of another in cold blood, as he did, is beyond my comprehension, no matter what their crime. Even if a method could be devised which was entirely painless, it's sinister and wrong IMO.
