If Bin Ladin were captured, I would expect the news to kept on the q.t. until it was strategically advantageous to announce it.
Even if he wasn’t captured, it might still be a good story to convincingly put out as disinformation to perhaps smoke him out.
But if it were an undisputable fact that Bin Ladin was captured, then just put him in a cage and put him on display coast to coast.
Guys like Bin Ladin hate to be mocked, that would be more damaging to him- and more important, his movement- than it would be to just kill him.
