Our greatest responsibility is the active defense of the American people. Twenty-eight months have passed since September 1lth, 2001—over two years without an attack on American soil. And it is tempting to believe that the danger is behind us. That hope is understandable, comforting and false. The killing has continued in Bali, Jakarta, Casablanca, Riyadh, Mombassa, Jerusalem, Istanbul, and Baghdad. The terrorists continue to plot against America and the civilized world. And by our will and courage, this danger will be defeated.
Inside the United States, where the war began, we must continue to give our homeland security and law enforcement personnel every tool they need to defend us. And one of those essential tools is the Patriot Act, which allows federal law enforcement to better share information, to track terrorists, to disrupt their cells, and to seize their assets. For years, we have used similar provisions to catch embezzlers and drug traffickers. If these methods are good for hunting criminals, they are even more important for hunting terrorists. Key provisions of the Patriot Act are set to expire next year. The terrorist threat will not expire on that schedule. Our law enforcement needs this vital legislation to protect our citizens. You need to renew the Patriot Act.(2004 State of the Union Address—President George W. Bush)
