The September 11, 2001 attack by the Al-Qaida terrorists was a great challenge to the American government than any other disaster that had occurred in the past decades. The government was threatened to an extent that any possible future attacks that had been suggested by this terrorist group had to be dealt with before it could actually be perpetrated against the American citizens. Since the days of 9/11, the nation has spent a reported $635.9 billion on homeland security and has implemented many changes, strategies and processes to better prepare our nations Security. The government had few institutions that would have coped with this disaster before it happened but thereafter, it has moved towards solving this problem by establishing several institutions and initiatives including the U.S.A. Patriot Act, the Homeland Security Act, the Department of Homeland Security, the National Incident Management System, Homeland Security Presidential Directives 5 and 8, and the Transportation Security Administration, all aimed at countering any intended attacks whether within the country or abroad. Their implementations are at local level as well as state and federal level.
The USA Patriot Act signed in October 26, 2001 as a response to the 9/11 terrorist attacks was aimed at reducing limitations to law agencies to search e-mail communications, telephone conversations and messages, and financial or medical records for purposes of gathering intelligence within the United States’ territory (United States Government Accountability Office, 2011). The Act also expanded the extent to which government law enforcers could search individuals without informing them prior to the search either at their homes , cars, or any other place which was earlier prohibited by law. The courts authority to order law enforces not to search a particular area or individual suspected to be in possession of terrorist-related materials was also minimized
