we hit upon meta data. meta data, defined as information about a communication.all to, from, when how long. despite what the judge said about assistance and constitutional protectance, the controlling legal authority is smith versus maryland 1979 which the supreme court held 5 to 3 that meta data constitutionally protected. and we therefore struck upon it again as the gentlest way as we which we balance the two demands of our constitution, your security and your liberty. there were other tools available. we were accused of using some of these other tools. the judge came close to accusing us of those other tools just a few minutes ago. we were accused of having a drift net over deerborn michigan or freemont california and sucking up the content of phone calls of american citizens and then searching those phone calls for keyword searches, looking for words like bomb and things like that. that never happened. we never got to content. by the way we never even collected the meta data. there were no metaphorical alligator clips on metaphorical wires here. we actually g

of picture so we can put the metadata, because it's a database that's searchable, so we need the meta data and if photographs come with this information, we first choose those. bill: what about other things on the website, in terms of you've got photographs, oral history interviews, what else is on there? professor han: there are many writings about the korean war, and also we are trying to connect with the young generations, because there is a tremendous lesson out of the korean war, so we are trying to connect with the young generation using online social media. so we're using facebook, twitter, instagram, constantly introducing pictures and artifacts to younger generations. one more important thing, in american history textbook, there are only one paragraphs covering on the korean war. in this workshop that i invited the descendents of the korean war veterans, i'm trying to educate them so that our textbook can cover more about an importance of the korean war. bill: jon

i have taken heat from you libertarians because i say that obama says it is just meta data it's not yourersonal phone call and it might stop terrorism. (crowd booing) >> educate me. >> the government's collection is just as dangerous in the contact. >> i would think that's the bad thing but meta data is equally bad. people need to understand what you can do all your life. they can figure out who you are calling they can figure out if you have a medical condition. think about all of the phone records you have and all of the ways in which the government can decipher based on who you are calling, when you are calling them and how long you are talking to them what you are doing each day. >> your fellow republican former house committee chairman says this program is used to stop a terrorist attack in the last few years. people do want to kill us. >> there are people who would say just the opposite. he would say this program hasn't been affect tive it is not useful. even if it were affected once in a while we have a constitution we have to follow. (applause) >> just one more question you are p

. >> meta-data means basic records about a communication: phone numbers, when calls are placed and how long they last. >> you don't have to have done anyting wrong, you simply have to eventually fall under suspicion from somebody even by a wrong call. and then they can use this system to go back in time and scrutinize every decision you've ever made. >> the documents also showed that the nsa was listening to the phone calls of world leaders. >> i think the best way to summarize the nsa surveillance mindset is to quote general alexander who runs the agency. he had a motto when he was in iraq, in charge of surveillance of the iraqi population against whom the united states waged war, which was, collect it all. >> what do you say to the people who are like, i don't do anything wrong, i don't care if they see my emails or hear my calls? people who say that don't actually believe it. they put locks on their bedroom and bathroom doors. every time somebody says to me i have nothing to hide, i don't care about privacy, i always say to them, please give me all the passwords to your email accoun

offered by congressman that said i think the right guidelines barred the government from collection of meta data but gave them the opportunity to do what they need to gather the information to investigate terrorist plots that can take place in the united states and elsewhere in the world. >> congressman, lay out the next two days when president asks congress for authority for more military force. how does this play out this upcoming week? >> we should take that and look at it very carefully. i don't think we need to rush into giving a very quick response. remember the president has had a mixed record here. he did not seek authorization for use of military force to go to libya. many complications have insued from that. he thought authorization to go into syria against the current syrian government. that got a negative response from the congress. i think there's more open mindedness now about finding the right balance here in terms of giving him authority he needs without us stepping out in front of these middle eastern nations like jordan that need to take the lead in protecting their region and

connecting to a broader infrastructure that itself enables all kind of tracking opportunities and meta datallection and potentially content collection, then the device -- it doesn't matter what the device is. some of these questions ultimately need to be addressed as an infrastructural level. it is not enough to say well we can build this one tool. we need to say if we want people to be able to have secure communications the fundamental networks and protocols, the ways they talk online to each other, those mechanisms need to be secured and need to provide people with the ability to have the confidential communications and the ability to operate privately on the networks. because the ability to have that kind of all-seeing analysis into these tools is actually makes everyone in the involved in the network massively insecure. it is not possible. and this is well understood within the engineering community. that it's not possible to actually engineer broad scale surveillance mechanisms to allow just the good guys to surveil. you simply can't build the protocols. you can't build the networks in

. >> it seems like you asked the obama administration realized the collection of meta data for several years by the government was sort of an overreach. >> i'm not sure. i think you've heard the president say -- what we're talking about here is the potential for abuse on the one hand. potential for abuse on the one hand. but they haven't said they found actual abuse which i think is an important report and a very different place than where we stood, say, after the church report, where we found information being used for improper purposes. here there was a potential of abuse because of the amount of information that you're collecting and on the other hand you're balancing that against the potential to prevent terrorist attacks. looking at that balance, i think what you find is that there's another way to achieve that goal, which is what they've called for in the legislation. there are important national security implications for that type of information. there's another way to get it that doesn't involve, in that instance, the government holding the data so it decreases the potential fo

. >> since you brought that up, do you think that the current, for instance, meta-data collection, did they get that balance right? >> i think, number one, metadata collection generates value for the nation. i believe that. it does generate value for the nation. what is it a silver bill -- but is it a silver bullet? doesn't guarantee that there will never be another 9/11? no. that is the criterion you want to use, it is not a silver bullet. it is one component of a broader strategy designed to enhance security. at the same time, we also realize that in executing that phone record access, we need to do it in a way that engenders confidence in our system, that it is being done on a lawful basis, with a specific framework, and that there are measures in place to ensure that nsa or others, are not abusing their access to the data. that is fair and right for us as a nation. >> i would like you to quantify the value that is generated for the nation. early on, when the report -- the administration bandied about a figure. 50 plus. that figure was whittled down to a far smaller number, where th
