A Question

This afternoon the US attempted to eliminate Saddam by dropping almost four tons of bombs on an apartment block in a residential neighbourhood, levelling it. It's unknown whether Saddam survived, or even if he was there in the first place. The attack killed at least 14 civillians, and there's bound to be more under the rubble (and of course there's the ones they only find bits of - a foot here, a tooth there...)

So, a question: how many innocent bystanders is a chance to kill Saddam worth? And would your answer change if those people were Americans?
