This document discusses definitions of terrorism from different perspectives and their implications. It examines definitions from international bodies, governments, law enforcement, counterterrorism groups, legal systems, and academics. While a universal definition has been elusive due to different biases and goals, the document emphasizes that terrorism involves premeditated violence against non-combatants for political, social, or psychological goals. Legal definitions are important for successful investigation and prosecution of terrorists, but they must balance security with civil liberties. Education is also discussed as significantly impacted by terrorism.
