put it bluntly, that was crazy! What's good for the mob should be good for terrorists." (Cong. Rec., 10/25/01) Allows law enforcement to use surveillance against more crimes of terror. Before the Patriot Act, courts could permit law enforcement to conduct electronic surveillance to investigate many ordinary, non-terrorism crimes, such as drug crimes, mail fraud, and passport fraud. Agents also could obtain wiretaps to investigate some, but not all, of the crimes that terrorists often commit. The Act enabled investigators to gather information when looking into the full range of terrorism-related crimes, including: chemical-weapons offenses, the use of weapons of mass destruction, killing Americans abroad, and terrorism financing. Allows federal agents to follow sophisticated terrorists trained to evade detection. For years, law enforcement has been able to use "roving wiretaps" to investigate ordinary crimes, including drug offenses and racketeering. A roving wiretap can be authorized by a federal judge to apply to a particular suspect, rather than a particular phone or communications device. Because international terrorists are sophisticated and trained to thwart surveillance by rapidly changing locations and communication devices such as cell phones, the Act authorized agents to seek court permission to use the same techniques in national security investigations to track terrorists. Allows law enforcement to conduct investigations without tipping off terrorists. ]
