Sure, take his/her records...we won't tell.
Verizon Says It Turned Over Data Without Court Orders - washingtonpost.com
Verizon also disclosed that the FBI, using administrative subpoenas, sought information identifying not just a person making a call, but all the people that customer called, as well as the people those people called. Verizon does not keep data on this "two-generation community of interest" for customers, but the request highlights the broad reach of the government's quest for data.
From January 2005 to September 2007, Verizon provided data to federal authorities on an emergency basis 720 times, it said in the letter. The records included Internet protocol addresses as well as phone data. In that period, Verizon turned over information a total of 94,000 times to federal authorities armed with a subpoena or court order, the letter said. The information was used for a range of criminal investigations, including kidnapping and child-predator cases and counter-terrorism investigations.
Verizon and AT&T said it was not their role to second-guess the legitimacy of emergency government requests.
