Is Americans being beheaded on tv is ok?

We watched Bin Ladens doings on TV as they blindfolded and executed our Americans. Even went as far as beheading our soldiers. That was ok to post on you tube and cnn. Why has the news not argued that point? We can watch our loved ones die but not the monster that made it happen. I would love to see the with a hole in his head. You can still pull up Saddam Hussein being hanged our soldiers were over seas during that point of time hummm. I never doubted the fact until the dispute over the pictures we see worse on 48 hours or law and order.
