place? that s exactly right. and quite specific intelligence that not only were terrorist groups trying to manipulate or find the loopholes in the system, but they had possibly taken equipment to test it. in some ways this shouldn t be a surprise, for every defensive move the u.s. takes, the terrorists try to work afternoon it. and the challenge, as we re seeing and you just saw basically in that tsa statement is that domestically, 2 million people are flying a year, there s 100,000 flights a day globally. the size of our aviation network is so huge, that the more security you put on it, the slower it will get and potentially stop huge commercial activity. so the lap top ban which may have its flaws seems in response to this. but it does beg a bigger question, which is if this is a vulnerability, why wouldn t you either prohibit all lap tops or have better screening processes.
