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.
