Terrorism has been on the face of the world for centuries, but not until only foreign policies and security strategies but also legal issues became a matter of controversy. After 9/11, Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism [1] H.R. 3162, S. 1510, Public Law 107-56 became a United States legislative law, enacted in response to the September 11, 2001 terrorist attacks. Patriot Act's most notorious provision, Section 215, the so-called “angry librarians” provision allows federal agents to ask The Foreign Intelligence Surveillance Court to issue an order directing the recipient to produce tangible things in national security and terrorism cases. There are many criticisms for this provision. There are two obligations for the government: to protect civil safety and security against violence, and to preserve civil liberties. One should not be preferred over the other . They are supposed to work parallel to each other. If the government leaves one of them behind, the system will lose its equilibrium level.
