Another reason not to piss off the man

The man sees everything.

The C.I.A. dispatches undercover officers overseas to gather intelligence today roughly the same way spies operated in biblical times. But the N.S.A., born when the long-distance call was a bit exotic, has seen its potential targets explode in number with the advent of personal computers, the Internet and cellphones. Today’s N.S.A. is the Amazon of intelligence agencies, as different from the 1950s agency as that online behemoth is from a mom-and-pop bookstore. It sucks the contents from fiber-optic cables, sits on telephone switches and Internet hubs, digitally burglarizes laptops and plants bugs on smartphones around the globe. 

Mr. Obama and top intelligence officials have defended the agency’s role in preventing terrorist attacks. But as the documents make clear, the focus on counterterrorism is a misleadingly narrow sales pitch for an agency with an almost unlimited agenda. Its scale and aggressiveness are breathtaking.
