This is really great news. I'm only surprised they announced it so quickly. I would have imagined that there was a lot of actionable intel in all that was seized. It seems kind of quick to have already exploited it . . . unless they've announced it to get others to panic and run.
In any event, this gives me some expectation for further raids in the near future. It would not surprise me if OBL is holed up in one of the madressah "schools" somewhere, like in Karachi, for example.
Actually, they announced it only hours after the arrest. I guess that it was impossible to keep a low profile as too many witnessed the raid.
