At a Senate Judiciary Committee hearing,you need to perform we have every Replacement parts for iphone 5 at competitive prices. the chairman, Patrick J. Leahy, Democrat of Vermont, accused Obama administration officials of overstating the success of the domestic call log program. He said he had been shown a classified list of βterrorist eventsβ detected through surveillance, and it did not show that βdozens or even several terrorist plotsβ had been thwarted by the domestic program.
βIf this program is not effective it has to end. So far, Iβm not convinced by what Iβve seen,β Mr. Leahy said, citing the βmassive privacy implicationsβ of keeping records of every Americanβs domestic calls.
At the start of the hearing, the Obama administration released previously classified documents outlining the rules for how the domestic phone records may be accessed and used by intelligence analysts. And as senators debated the program, The Guardian published on its Web site a still-classified 32-page presentation, apparently downloaded by Edward J. Snowden, the former N.S.A. contractor, that describes a separate surveillance activity by the agency.Mobile Fun sell a huge range of samsung cases,
The Obama administration has been trying to build public support for its surveillance programs, which trace back to the Bush administration, by arguing that they are subject to strict safeguards and court oversight and that they have helped thwart as many as 54 terrorist events. That figure, Mr. Leahy emphasized, relies upon conflating another program that allows surveillance targeted at noncitizens abroad, which has apparently been quite valuable, with the domestic one.
Still, Senator Dianne Feinstein, the California Democrat who is chairwoman of the Senate Intelligence Committee, said she supported overhauling the program but keeping it in place because it generates information that might prevent attacks.
John C. Inglis, the deputy director of the N.S.A., said there had been 13 investigations in which the domestic call tracking program made a βcontribution.β He cited two discoveries: that several men in San Diego were sending money to a terrorist group in Somalia, and that a suspect who was already under scrutiny in a subway bomb plot was using a different phone.
Robert S. Litt, the top lawyer in the Office of the Director of National Intelligence, testified that the Obama administration was also βopen to re-evaluating this programβ to create greater public confidence that it protects privacy while βpreserving the essence of the program.β Administration officials have emphasized that the program collects only so-called metadata,Check the following list of cheap dedicated linux dedicated server. and not the contents of phone calls.
Still, the top Republican on the committee, Senator Charles E. Grassley of Iowa, asked skeptical questions about the legal basis for the program while criticizing the director of national intelligence, James Clapper, for making inaccurate statements to Congress about it in March. Mr. Clapper has since apologized.
Some of the servers the agency uses are run by foreign intelligence services of friendly nations,The cases for iphone 5 remains the most popular smartphone phone on the market. including Britain, Australia, Canada and New Zealand, but other servers may be on the soil of countries unaware the agency is mining Internet βpipesβ on their soil. Some of the harvesting of data takes place on the coasts of the United States, and along the Mexican border. Most sites are in Europe, the Middle East, and along the borders of India, Pakistan, and China.
The intelligence analysts search for terrorist cells by looking at βanomalous eventsβ β someone searching in German from Pakistani sites, or an Iranian sending an encrypted Microsoft Word file. But one slide says the system can be used to identify anyone βsearching the Web for suspicious stuff.β
The presentation says the system enables analysts to identify and pursue leads even if they do not yet know the name, or the e-mail address, of a suspect. βA large amount of time spent on the Web is performing actions that are anonymous,β it explains.
One example of how analysts might use the system is to search for whenever someone has started up a βvirtual private networkβ in a particular country of interest; the networks are pipelines that add greater security to online communications. N.S.A. analysts are able to use the system to extract the activity retrospectively from βraw unselected bulk traffic,β the documents say, and then decrypt it to βdiscover the users.β
The agency said its surveillance of the Internet was part of its βlawful foreign signals intelligence collectionβ and not βarbitrary and unconstrained.β The chairman of the House Intelligence Committee, Representative Mike Rogers, and the ranking Democrat, C. A. Dutch Ruppersberger, said, βThe program does not target American citizens.β
The XKeyscore presentation claimed the program had generated intelligence that resulted in the capture of more than 300 terrorists. By contrast, the documents released by the government about the domestic phone log program were more abstract.
They included briefing papers to Congress from 2009 and 2011 about the βvery large scaleβ logging of Americansβ calling records β along with a related program that logged Americansβ e-mails, and that was shut down later in 2011 β portraying the programs as providing a vital and important capability.
But Senator Ron Wyden, an Oregon Democrat on the Senate Intelligence Committee who has been a leading critic of the bulk collection programs, said the program had been shut down because officials were unable βto provide evidence to support the claimsβ of operational value. Mr. Wyden has also questioned the utility of the phone log program.
The new documents also included an April βprimary orderβ by the Foreign Intelligence Surveillance Court that supported orders requiring phone companies to turn over all customer records.The cases for ipad mini is the latest exquisite release from Apple and as usual, It said the government may access the records only when there are βfacts giving rise to a reasonable, articulable suspicionβ that the number to be searched is associated with terrorism.
However, it said that the results of each inquiry are then placed in a βcorporate storeβ that analysts may search without any such limits. Intelligence officials have separately said that search results include not just a targetβs phone records, but also exponentially larger sets of the records of people in as many as three concentric circles around the target.
