The USA Patriot Act aims to prevent terrorist acts and provide expanded law enforcement protection.

In October 2001, Congress passed the Patriot Act to expand law enforcement’s use of surveillance, including “roving wiretaps,” delayed-notice search warrants and search warrants covering a larger area to investigate crimes.

It provides more assistance for computer hacking victims by allowing computer crimes to be charged similar to physical trespassing.

The act also allows law enforcement to more easily coordinate with national defense and intelligence agencies to protect Americans and national security.

It imposes tougher penalties for those who commit or support terrorist crimes, including nuclear, chemical or bioterrorism, and it lengthens or eliminates the statute of limitations for certain terrorist crimes.
