This is not a crime, there is no court to assess damages, there is no jury of peers available.
it is a war, where the broadest meanings of justice are to be applied, but we are in no way constrained by calls for "evidence" "process" or anything else other than a need to prosecute our war against these people as effectively as needed.
The Taliban plaint for "evidence" and their offer to "try Osama" is a fig leaf game played by these Taliban tyrants in order to either lull the ignorant, deceive the willing or fool themselves.
What the Taliban does to its own people is cause enough to destroy their rule.
What Osama is already known to have done is sufficient reason to wreak havoc on him and his organization.
