Final answer:
The PATRIOT Act defines a terrorist as an individual suspected of involvement in international or domestic terrorism, allowing extended federal powers for surveillance.
Step-by-step explanation:
Under the PATRIOT Act of 2001, specifically the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act, a terrorist is defined as any individual suspected of possible involvement in international or domestic terrorism. This broad definition allowed for increased government surveillance and the monitoring of individuals deemed to be a threat. The Act consequently led to debates over the balance between national security concerns and the protection of civil liberties. It is known that terrorism aims to create fear for political, religious, or ideological goals, and the PATRIOT Act aimed to expand federal capabilities to address and prevent such threats.
