Mick :
Your experience reminds me of an evening where a fellow, just as you describe, was going on about what he would do to the supper grass, Harry Kirkpatric. Present was a volunteer who had undergone prolonged torture in a British prison. His eyes filled with tears and he said, "Until you've been tortured the way Harry was, you don't have the right to have an opinion on the subject. I hate what he did, and he has to be stopped from informing however it is done. But, until you have been tortured you don't have a right to sit here mouthing off about what you would do to him."
