Apparently Edward Snowden has given this testimony, remotely of course, before the European Parliament. It opens as follows:
I would like to thank the European Parliament for the invitation to provide testimony for your inquiry into the Electronic Mass Surveillance of EU Citizens. The suspicionless surveillance programs of the NSA, GCHQ, and so many others that we learned about over the last year endanger a number of basic rights which, in aggregate, constitute the foundation of liberal societies.
The first principle any inquiry must take into account is that despite extraordinary political pressure to do so, no western government has been able to present evidence showing that such programs are necessary. In the United States, the heads of our spying services once claimed that 54 terrorist attacks had been stopped by mass surveillance, but two independent White House reviews with access to the classified evidence on which this claim was founded concluded it was untrue, as did a Federal Court.
Looking at the US government's reports here is valuable. The most recent of these investigations, performed by the White House's Privacy and Civil Liberties Oversight Board, determined that the mass surveillance program investigated was not only ineffective---they found it had never stopped even a single imminent terrorist attack---but that it had no basis in law. In less diplomatic language, they discovered the United States was operating an unlawful mass surveillance program, and the greatest success the program had ever produced was discovering a taxi driver in the United States transferring $8,500 dollars to Somalia in 2007.
After noting that even this unimpressive success---uncovering evidence of a single unlawful bank transfer---would have been achieved without bulk collection, the Board recommended that the unlawful mass surveillance program be ended. Unfortunately, we know from press reports that this program is still operating today.
I believe that suspicionless surveillance not only fails to make us safe, but it actually makes us less safe. By squandering precious, limited resources on "collecting it all," we end up with more analysts trying to make sense of harmless political dissent and fewer investigators running down real leads. I believe investing in mass surveillance at the expense of traditional, proven methods can cost lives, and history has shown my concerns are justified.
Despite the extraordinary intrusions of the NSA and EU national governments into private communications world-wide, Umar Farouk Abdulmutallab, the "Underwear Bomber," was allowed to board an airplane traveling from Europe to the United States in 2009. The 290 persons on board were not saved by mass surveillance, but by his own incompetence, when he failed to detonate the device. While even Mutallab's own father warned the US government he was dangerous in November 2009, our resources were tied up monitoring online games and tapping German ministers. That extraordinary tip-off didn't get Mutallab a dedicated US investigator. All we gave him was a US visa.
Nor did the US government's comprehensive monitoring of Americans at home stop the Boston Bombers. Despite the Russians specifically warning us about Tamerlan Tsarnaev, the FBI couldn't do more than a cursory investigation---although they did plenty of worthless computer-based searching---and failed to discover the plot. 264 people were injured, and 3 died. The resources that could have paid for a real investigation had been spent on monitoring the call records of everyone in America.
This should not have happened. I worked for the United States' Central Intelligence Agency. The National Security Agency. The Defense Intelligence Agency. I love my country, and I believe that spying serves a vital purpose and must continue. And I have risked my life, my family, and my freedom to tell you the truth.
The NSA granted me the authority to monitor communications world-wide using its mass surveillance systems, including within the United States. I have personally targeted individuals using these systems under both the President of the United States' Executive Order 12333 and the US Congress' FAA 702. I know the good and the bad of these systems, and what they can and cannot do, and I am telling you that without getting out of my chair, I could have read the private communications of any member of this committee, as well as any ordinary citizen. I swear under penalty of perjury that this is true.
These are not the capabilities in which free societies invest. Mass surveillance violates our rights, risks our safety, and threatens our way of life. If even the US government, after determining mass surveillance is unlawful and unnecessary, continues to operate to engage in mass surveillance, we have a problem. I consider the United States Government to be generally responsible, and I hope you will agree with me. Accordingly, this begs the question many legislative bodies implicated in mass surveillance have sought to avoid: if even the US is willing to knowingly violate the rights of billions of innocents---and I say billions without exaggeration---for nothing more substantial than a "potential" intelligence advantage that has never materialized, what are other governments going to do?
Whether we like it or not, the international norms of tomorrow are being constructed today, right now, by the work of bodies like this committee. If liberal states decide that the convenience of spies is more valuable than the rights of their citizens, the inevitable result will be states that are both less liberal and less safe.
I will now respond to the submitted questions. Please bear in mind that I will not be disclosing new information about surveillance programs: I will be limiting my testimony to information regarding what responsible media organizations have entered into the public domain. For the record, I also repeat my willingness to provide testimony to the United States Congress, should they decide to consider the issue of unconstitutional mass surveillance.
