Land of freedom or land of surveillance? Right to privacy in the U.S. after 9/11 Abstract The United States of America has been always perceived as a land of freedom. The U.S. citizens are very proud of their Constitution that became model for other constitutions in the world. The terrorist attacks of September 11, 2001 not only brought a change in the U.S. foreign policy as the war on terror was launched, but also influenced the domestic political development and caused creation of a complex network of security legislative. These antiterrorism measures have been criticized, as the programs arising especially from the Patriot Act are controversial, challenging the civil rights and especially the right to privacy. In 2013, Edward Snowden revealed secret spying programs of the National Security Agency. This thesis examines the discrepancies between the proclaimed freedom and the reality, in which the United States is ranked among endemic surveillance societies.
