The Patriot Act has made a mockery of the 4th Amendment: "The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized." by allowing warrant-less wiretapping.
Now with the National Defense Authorization Act being passed by Congress the 5th Amendment is in threat. The act lets the military grab U.S. citizens for indefinite detention. http://www.huffingtonpost.com/2011/12/12/indefinite-military-detent...
