nick, thank you very much. it is a delicate balance. so fair and balanced. a guy who says the president might be compromising our security. national security analyst aaron cohen. you have heard that here in the quest for personal freedom and running in on trucetive behavior, we risk what, leaving ourselves open for attack or what? >> that's exactly what we risk, and the reason why is because the key to thwarting terrorist attack is intelligence and information, and not just intelligence but accurate, actionable intelligence, which can only be retrieved by mining data that is real time. and in this case it involved text messages. i've heard both sides of the argue. -- >> i don't know who is wright on this but what if the argument is, if that were so we would have seen more bang for the spying buck and all of this data mining would have resulted in a lot more arrests when in fact the number of arrest wes have seen of the al qaeda types since 9/11 are in large part to traditional efforts, none of this high-tech stuff. >> a good point. i think that two things. one, counterterrorism on the macro level is a thankless job. we're only remembered for our sole failure,
