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 be issued, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the person or things to be seized
~ 4th Amendment to the U.S. Constitution ~
The 4th Amendment is critically important. Today, many federal government agencies routinely ignore it and have no qualms about spying on American citizens. Examples abound: the IRS targeting Tea Party organizations, the FBI illegally spying upon political opponents, and the revelations of NSA spying on Americans.
All of these actions represent an unConstitutional violation of our liberties. These agencies should be investigated and held responsible for their actions.
