Drake volunteered to be a witness.
"Why did we launch the IG complaint? Out of total abject frustration. Knowing that we had something so important to share, and thought we had witnessed wrongdoing that needed to be addressed," Wiebe explained.
For two years, Drake was the most important witness for the inspector general. But in the end, the Department of Defense investigation was stamped "classified," which hid the Trailblazer debacle from public view.
As his frustration grew, Drake says he was shocked to learn about something else happening at the agency post 9/11: he learned of a top secret NSA program that became known as "warrantless wiretapping."
"It was no longer necessary to follow the law. A huge Pandora's Box had been opened up," Drake said.
On orders from the White House, the NSA was listening in on people in the United States, without a warrant from a judge.
"And this is where I began to have grave concerns about the decisions that were made to bypass the Constitution, willfully and deliberately, as a result of 9/11. I took my grave concerns up with the general counsel at NSA. I spoke with one of their lead attorneys. He said, 'Don't worry about it, Tom. It's all legal,'" Drake told Pelley.
"It was legal because the White House said it was legal?" Pelley asked.
"Yes," Drake said.
After four years of reporting through proper channels, Drake noticed that the Baltimore Sun newspaper had begun a series of articles about trouble at the NSA.
"There's one final step that could be taken. But it was fraught with significant risk," Drake remembered.
Anonymously, Drake contacted Sun reporter Siobhan Gorman and became an unnamed source for her, starting with an article about Thin Thread, headlined "NSA Shelved Better Program That Sifted Calls." Another article told readers that mismanagement at the NSA continued years after 9/11.
Drake denies he ever communicated classified information to Siobhan Gorman. "Not once ever. That was one of the fundamental rules. Whether it was oral communication, whether it was written, electronic or later on, even in hard copy. It was all unclassified. Period," he told Pelley.
But after the articles, the FBI raided the homes of all the people who had filed that confidential complaint with the Defense of Department inspector general asking for the Trailblazer investigation - Kirk Wiebe, Bill Binney and Diane Roark.
"They came busting in. I was in the shower at the time. And one of them came running up and was pointed a gun at my eyeballs. And pulled me out of the shower," Binney remembered.
But only Drake was charged. He is being advised by the Government Accountability Project, a Washington legal organization that defends whistleblowers. Drake told us that he knew he had violated a confidentiality agreement with the NSA and he thought he might lose his job, but the prosecutors charged him under the Espionage Act - not for divulging classified information, but for taking classified papers home without permission. He faces up to 35 years.
