Listening to Aid Workers

NSA awarded Adrienne Kinne a NSA Joint Service Achievement Medal in 2003 at the same time she says she was listening to hundreds of private conversations between Americans, including many from the International Red Cross and Doctors without Borders.

"We knew they were working for these aid organizations," Kinne told ABC News. "They were identified in our systems as 'belongs to the International Red Cross' and all these other organizations. And yet, instead of blocking these phone numbers we continued to collect on them," she told ABC News.

WATCH Kinne describe how listening to aid workers was part of the job.

A spokesman for Doctors Without Borders, Michael Goldfarb, said: "The abuse of humanitarian action through intelligence gathering for military or political objectives, threatens the ability to assist populations and undermines the safety of humanitarian aid workers."

Both Kinne and Faulk said their military commanders rebuffed questions about listening in to the private conversations of Americans talking to Americans.

"It was just always, that , you know, your job is not to question. Your job is to collect and pass on the information," Kinne said.

Some times, Kinne and Faulk said, the intercepts helped identify possible terror planning in Iraq and saved American lives.

"IED's were disarmed before they exploded, that people who were intending to harm US forces were captured ahead of time," Faulk said.

NSA job evaluation forms show he regularly received high marks for job performance. Faulk left his job as a newspaper reporter in Pittsburgh to join the Navy after 9/11.

Kinne says the success stories underscored for her the waste of time spent listening to innocent Americans, instead of looking for the terrorist needle in the haystack.

"By casting the net so wide and continuing to collect on Americans and aid organizations, it's almost like they're making the haystack bigger and it's harder to find that piece of information that might actually be useful to somebody," she said. "You're actually hurting our ability to effectively protect our national security."
