Retired CIA officer turned political activist Ray McGovern examines whether 4th Amendment guarantees “against unreasonable searches and seizures” have become part of the debris of 9/11.

In his talk, Speaking Truth to Power, McGovern draws on his 27 years as an intelligence analyst — topped by a visit with Edward Snowden in Russia last fall — to question the political manipulation of vital intelligence, the National Security Agency’s collection of millions of Americans’ phone records, and the future of American security and civil liberties.

As a CIA analyst during a period spanning the administrations of John F. Kennedy to George H. W. Bush, McGovern has chaired National Intelligence Estimates and prepared the President’s Daily Brief.
