The U.S. Patriot Act that of September 11, 2001 attacks plays a critical role and a leading role in various operations to save innocent Americans from harm. In regard to intelligence sharing environment, this act has allowed investigators to use the necessary tools to aid their investigations. In section 203 (b), the Patriot Act approves the sharing of foreign intelligence information. For instance, significant legal barriers that hindered the intelligence, the law enforcement, and national defense communities from coordinating and talking to protect national security and Americans were removed.
