Consider it in light of what Zarqawi's group does with bodies. In one Iraqi town they killed several young men, cut off their heads, and placed them in the middle of town with a note pinned to them saying whoever moved them would end up the same way.
One boy's father couldn't bear it and went to get the body, not realizing that they had removed the organs and stuffed the body with explosives. When the father moved it, it killed him too. Other times they have purposely left bodies where they could be found without the head, to make the impact on the family and the overall terror more effective.
So, frankly, I think we should hang zarqawi's body out in front of the white house dressed in a clown nose, big shoes, and a tutu; his genitals tucked neatly in his mouth. I'm tired of fighting people with one hand tied behind our backs out of some faux-idealism.
