Q&A: Surveillance of phone records
What information is being obtained?
The order called it "metadata" that consisted of telephone numbers and the times and duration of calls, but not the contents of the phones calls or the names and addresses of those who owned the phones.
How does the government get access to this mass of data?
Through a court order and by relying on a provision in the USA Patriot Act. It says the government may obtain business records, phone records or other "tangible things" by going to a special court and "showing that there are reasonable grounds to believe that the tangible things sought are relevant to an authorized investigation."
Who decides on these requests?
The Foreign Intelligence Surveillance Court, whose judges operate in secret. They are appointed by Chief Justice John G. Roberts. It was Judge Roger Vinson from Florida who approved the order for Verizon phone records.
Is it constitutional for the government to secretly obtain the phone records of ordinary Americans?
Probably. The Fourth Amendment forbids "unreasonable searches" by the government, but the Supreme Court has drawn a sharp distinction between what is truly private and what is not. When people talk on the phone, that is a private conversation, the court said, and it is protected by the Constitution. So, before police can "wiretap" a phone call, they must persuade a judge to give them a search warrant. This requires showing they have "probable cause" to believe a crime is in progress. But in the 1970s, the court said business records, tax records and phone records are not truly private. These records circulate through offices and through the mail. Because such records are not protected under the Fourth Amendment, a police official or FBI agent may obtain them by sending an order to a business saying they are needed for an investigation.
Is there any legal limit on what records the government may secretly obtain?
That is not clear. Before this week, many had assumed the law limited the government to obtaining only records that were "relevant to an authorized investigation." These words from the Patriot Act were read to mean officials were tracking certain people because they were suspected of involvement in terrorism. But Vinson's order made no mention of an actual investigation. He said Verizon must turn over "all call detail records," including "local calls . . . wholly within the United States."
Justice Department lawyers have not explained in public their interpretation of the law. Some outside experts say they must take the view that having access to the entire database of phone calls is "relevant" to investigating terrorism plots.
"This is all about searching for patterns of calls," said Washington attorney Stewart Baker, a former general counsel for the National Security Agency. He said he had no actual knowledge of the current program, but he said having access to the phone records would allow the NSA to link calls to suspected terrorists, here or abroad.
