Big Al Qaida Arrest?

Pakistan is claiming again that they have caught OBL's number two man. We've heard before that Zawahri had been trapped in Pakistan so I'll wait for some visual evidence. But this would certainly be a major blow to al Qaida and OBL if it's true. And, I would hope that after the last blunder concerning the supposed capture of this man, that Pakistan would be very careful before announcing anything.
