Look how it's being used in the courts to overturn the Bill of Rights! Civil rights are no longer valid legal recourse--inadmissible. The Patriot Act itself violates the Constitution. As an unconstitutional document it is therefore an illegal document as well as a direct assault on individual liberty, self-determination and the rights of individuals. Its very unconstitutionality cannot even be challenged in the courtroom under the threat of disbarment. That's how radically it has impoverished our "Justice System".
Of course, with terrorism as a possibility, the Patriot Act was passed in order to see if it could be headed off. In doing that, though, we have seen a number of rights of American citizens violated. We no longer assume privacy in almost any venue, and are not surprised to know that the government is watching us all the time.
The Patriot Act violates civil liberties by enabling unwarranted wire tapping leading to abuse by authorities, under the pretense of curbing terrorism. Although it's unknown how far reaching the abuse really goes, information concerning the unconstitutional violation of civil rights by the NSA, DEA and other security administrations is constantly being revealed by the media.
Any one can be a terrorist, even the members of Al-Qaeda were once innocent. If we want to stop 9-11 from happening again we need to continue this. Even so you must make the choice: Do you want to have what seems like an infringement on your civil liberties or would you rather take your own stand against these terrorist groups and most likely wind up dead?
