Without question. In fact, that goes for any of the terrorists. The only problem would be that it would be far too quick and painless to shoot them.
I'd sleep the sleep of the innocent too.
Edited to add:
On second thought here is what I'd do.
I would have the prick dig his own grave. Then I'd tie him to a sturdy post. At that point I'd bring in the live pig and butcher it in front of him, dumping the offal in the grave. I'd make sure the interpreter explained the ongoing process to Osama...that he clearly understood that in a few moments, his carcass would be resting on top of the pig's guts...and the rest of the pig would soon follow.
Only then, when the full impact of his impending death had sunk in would I kill him. I would then dump his sorry dead carcass in the hole and bury him.
I'd make sure that the entire ceremony was well recorded then send copies to Al Jazeera and to the rest of the Islasmofacists world wide wiht the clear and unabiguous explanation that THIS is what awaits you guys...NOT paradise with the 72 virgins...but eternal hell and damnation. So...bring it on!
THAT is what I'd do.
