The Supreme Court won't hear an appeal from a public interest group seeking to get internal records from the Department of Homeland Security about its protocol for shutting down wireless networks during emergencies.
 
The justices on Monday let stand an appeals court ruling that said the agency could refuse to release the documents under an exception to the Freedom of Information Act for disclosures that could endanger lives.

The Electronic Privacy Information Center argued that the appeals court construed the law too broadly so that the government could conceal any records by claiming they concern security measures.

The U.S. Court of Appeals for the District of Columbia Circuit said the agency didn't need to specify exactly whose life would be endangered.
