THE BURNED OVER DISTRICT

And through its continued existence, the NSA continues to have no restrictions on how it can snoop on Americans as long as it can cobb up a foreign connection.

The Senate passed a bill on Thursday to reauthorize a powerful government authority to conduct foreign surveillance on U.S. soil, sending the president a six-year extension of the program just one day before a statutory deadline.

The 65-to-34 vote on the legislation, which the president is expected to sign into law, marks the end of a months-long debate that exposed sharp divisions between privacy advocates and national security hawks in Congress. Lawmakers have struggled over whether to limit the spy authority the intelligence community has identified as one of its most important surveillance tools.

The program, known as Section 702 of the Foreign Intelligence Surveillance Act, allows the National Security Agency to collect from U.S. companies the emails and other communication of foreign targets located overseas. But federal law enforcement agents can scour the database for information about Americans who have been in touch with those foreign targets, and many lawmakers wanted to force the government to obtain a warrant before doing so.

The legislation that passed the Senate on Thursday, and the House last week, requires law enforcement agents to procure a court order before they view the content of database searches for information about Americans, if they want to later use what they find in criminal cases. There is no such restriction in cases involving counterterrorism, counterintelligence and counterespionage.

Efforts to impose more stringent limits failed in both chambers. In the House, proponents of tighter privacy controls were unable to gain enough support for an amendment that would have required the government to secure warrants for database searches. In the Senate, opponents’ efforts to stymie progress also fell short this week, when senators eked out just enough votes to move the bill over an important procedural hurdle despite a last-minute call from Senate Minority Leader Charles E. Schumer (D-N.Y.) to slow down the debate and consider amendments to the measure.

Section 702 was the pillow on the face of the 4th Amendment which had provided some protection against warrantless search and seizure. Its elimination held out slim hope of the resurrection of the 4th but now there is nothing.
