Jakey,
If you go back through the thread how many people are saying that he didn't cock-up big time? What I, and I think many others, take issue with is the use of emotive terms such as terrorism and murder. The statement that the lives of military personnel are worth less than civilians was insulting beyond belief.
Why wasn't he prosecuted? Well it would appear that politics came into play there and politics are out with the remit of the military. Those decisions are made by the elected representatives of the people.
The CO and the crew of the Vincennes were doing their jobs, he and some others did it badly and a tragedy occurred, on that we can all agree I think.
