They had to shoot Osama bin Laden because he was not naked.

"Being naked was the only way Osama Bin Laden could have avoided being killed, it emerged today. The elite U.S. Navy Seals team that killed him was told to assume he was wearing a suicide vest if he was clothed, according to a briefing given to a congressional aide."

But he was in his pajamas, so, no matter what he did, he was doomed.

ADDED: Instapundit links, saying: "OTHER NIGHT I SHOT OSAMA IN HIS PAJAMAS. How I wound up in his pajamas I’ll never know...." That flickered through my head too.
