You are too kind AS, for if indeed I had contented myself to referring merely to his long sentence then I would have been technically correct for he was in fact sentenced to Life Imprisonment with Hard Labour. But of course I had to spoil it all by claiming that he "did a long stretch". Amazingly he served only one day at Fort Leavenworth and then a mere three and a half years of House Arrest before being released by a Federal Judge. All of the above was news to me and plucked from Wiki:
William Calley - Wikipedia, the free encyclopedia
He finally apologised for his role in the massacre to the Kiwanis Club of Greater Columbus as recently as 19th August 2009!
Not sure what all that does for my using him as an example. Given that many felt he took the rap for others in the CoC there is perhaps a continuing moral to his tale, not least in the naming of people by Mr Hadden-Cave QC in the Nimrod Report. Many are conspicuous there too by their absence!
