Again, I'll say it. He and others earned the right. I guess it is hyperbole. I wouldn't really urinate on someone's grave. And I certainly wouldn't spit in someone's face. I am glad he will not be charged, and I hope he was able to release his years of frustration and anger with the traitorous *itch.
All hat and no cattle. I would have no problem of urinating on Hitler's grave, spitting in Julius and Ethel Rosenberg's face, or worse to someone who caused the death of my child. Never say never. You sound like Dukakis and what he would do if someone raped his wife.
I get a little tired of those who sit in the comfort of their well protected, secure homes and preach on how others should act on the battlefield as a soldier or on the streets as a policeman. Jane Fonda evokes visceral reactions from many of us, who recall vividly what she did during the Vietnam era. If you understand the emotional aspect of this, you will understand why many of us are not upset by the rather innocuous gesture of spitting on someone whom we consider to be a traitor.
