Hypocrisy starts with the cash flow

Nsa"During the past decade, the NSA has secretly worked to gain access to virtually all communications entering, leaving, or going through the country. A key reason, according to the draft of a top secret NSA inspector general’s report leaked by Snowden, is that approximately one third of all international telephone calls in the world enter, leave, or transit the United States.

“Most international telephone calls are routed through a small number of switches or ‘chokepoints’ in the international telephone switching system en route to their final destination,” says the report. “The United States is a major crossroads for international switched telephone traffic.” At the same time, according to the 2009 report, virtually all Internet communications in the world pass through the US. For example, the report notes that during 2002, less than one percent of worldwide Internet bandwidth—i.e., the international link between the Internet and computers—“was between two regions that did not include the United States.”
Accessing this data is possible through a combination of techniques, through the most effective of them, the NSA can gain direct access to the fiber-optic cables that now carry most kinds of communications data. According to a slide released by Snowden, the cable-tapping operation is codenamed “UPSTREAM” and it is described as the “collection of communications on fiber cables and infrastructure as data flows past.” It also appears to be both far more secret and far more invasive than the PRISM program revealed by Snowden. Although PRISM gives the NSA access to data from the individual Internet companies, such as Yahoo, Google, and Microsoft, the companies claim that they don’t give the agency direct access to their servers. Through UPSTREAM, however, the agency does get direct access to fiber-optic cables and the supporting infrastructure that carries nearly all the Internet and telephone traffic in the country.
As part of its cable-tapping program, the NSA has secretly installed what amount to computerized filters on the telecommunications infrastructure throughout the country. According to the leaked inspector general’s report, the agency has secret cooperative agreements with the top three telephone companies in the country. Although the report disguises their names, they are likely AT&T, Verizon, and Sprint:
NSA determined that under the Authorization it could gain access to approximately 81% of the international calls into and out of the United States through three corporate partners: Company A had access to 39%, Company B 28%, and Company C 14%.
The filters are placed at key junction points known as switches. For example, much of the communications—telephone and Internet—to and from the northwestern United States pass through a nearly windowless nine-story building at 611 Folsom Street in San Francisco. This is AT&T’s regional switching center. In 2003, the NSA built a secret room in the facility and filled it with computers and software from a company called Narus. Established in Israel by Israelis, and now owned by Boeing, Narus specializes in spyware, equipment that examines both the metadata—the names and addresses of people communicating on the Internet—and the content of digital traffic such as e-mail as it zooms past at the speed of light.
The agency also has access to the telephone metadata—the numbers called and calling and other details—of all Americans. Phone calls from telephone numbers that have been selected as targets can be routed directly to the agency and recorded. According to William Binney, the former NSA senior official, the NSA has established between ten and twenty of these secret rooms at telecom company switches around the country."
