As time passes since the attacks of September 11, 2001, homeland security has improved, but concerns over privacy and civil liberties have increased. Advocates for security claim that new technologies and techniques in homeland security are necessary to protect the public. Privacy advocates believe that the mining of personal information and increased surveillance have negatively altered the American way of life. The Constitution of the United States of America is the foundation of American law. The first 10 amendments to the Constitution, known as the Bill of Rights, along with the Fourteenth Amendment form the basis of criminal procedure. These amendments establish limitations upon the actions of government in policing, investigating, and prosecuting crime and in punishing offenders. One of the most important issues for law enforcement balancing these limitations investigating crime. Review the First, Fourth, Fifth, Sixth, and Fourteenth Amendments to the Constitution and determine if Congress has the power to override the Constitution and pass laws to allow the National Security Agency and other government agencies to review phone calls, mine data and personal information, and otherwise invade the privacy of people within the United States, without probable cause.
