— Fourth, prosecuting CIA officers risks chilling current intelligence operations. This country faces an array of serious threats. A prosecution or extensive investigation will be an unmanageable expense for most CIA officers. More significant, their colleagues will become reluctant to take risks. What confidence will they have when their senior officers say not to worry, “this has been authorized by the president and approved by Justice”? And such reactions would be magnified if prosecutions focus only on the lower-ranking officers, not those in the chain of command. Such prosecutions are likely to create cynicism in the clandestine service, which is deeply corrosive to any professional service.

— Fifth, prosecutions could deter cooperation with other nations. It is critical that we have the close cooperation of intelligence services around the world. Nations often work together through their intelligence services on matters of mutual interest, such as combating terrorism, even if political relations are strained or nonexistent. The key to this cooperation is the ability of the United States to be a reliable partner and keep secrets. Prosecuting CIA officers undermines that essential element of successful intelligence liaison.

— Sixth, President Obama has decisively changed the policies that caused so much damage. He recognizes that it is vital to our security to have an effective intelligence community that is not distracted by looking backward and coping with congressional investigations and grand jury subpoenas.
