In the largest "fishing expedition" ever devised, the NSA uses powerful computers to "data-mine" the contents of these Internet and telephone communications for suspicious names, numbers, and words, and to analyze traffic data indicating who is calling and emailing whom in order to identify persons who may be "linked" to "suspicious activities," suspected terrorists or other investigatory targets, whether directly or indirectly.
But the government did not act-and is not acting-alone. The government requires the collaboration of major telecommunications companies to implement its unprecedented and illegal domestic spying program.
AT&T Corp. (which was recently acquired by the new AT&T, Inc,. formerly known as SBC Communications) maintains domestic telecommunications facilities over which millions of Americans' telephone and Internet communications pass every day. It also manages some of the largest databases in the world, containing records of most or all communications made through its myriad telecommunications services.
The lawsuits alleges that AT&T Corp. has opened its key telecommunications facilities and databases to direct access by the NSA and/or other government agencies, thereby disclosing to the government the contents of its customers' communications as well as detailed communications records about millions of its customers, including the lawsuit's class members.
