so, my biggest concern was, if i'm sending those guys in and murphy's law applies and something happens, can we still get our guys out? so that's point number one. these guys are going in... in, you know, the darkness of night, and they don't know what they're going to find there. they don't know if the building is rigged. they don't know if, you know, there are explosives that are triggered by a particular door opening. so huge risks that these guys are taking. and so my number one concern was, if i send them in, can i get them out? point number two was, as outstanding a job as our intelligence teams did-- and i cannot praise them enough; they... they did an extraordinary job with just the... the slenderest of bits of information-- to piece this all together. at the end of the day, this was still a 55/45 situation. i mean, we could not say definitively that bin laden was there. had he not been there, then there would have been some significant consequences. obviously, we're going into the sovereign territory of another country and landing helicopters and conducting a military operation
