Terrorism
Terrorism is, in the broadest sense, the use of intentionally indiscriminate violence as a means to create terror among masses of people; or fear to achieve a religious or political aim. It is used in this regard primarily to refer to violence during peacetime or in war against non-combatants. The terms "terrorist" and "terrorism" originated during the French Revolution of the late 18th century but gained mainstream popularity during the U.S. presidency of Ronald Reagan (1981–89) after the 1983 Beirut barracks bombings and again after the 2001 September 11 attacks and the 2002 Bali bombings.
Organized crime
There is no universally agreed, legally binding, criminal law definition of terrorism. Common definitions of terrorism refer only to those violent acts which are intended to create fear (terror), are perpetrated for a religious, political or ideological goal, deliberately target or disregard the safety of non-combatants (e.g., neutral military personnel or civilians), and are committed by non-government agencies. Some definitions also include acts of unlawful violence and war, especially crimes against humanity ("see the Nuremberg Trials"), Allied authorities deeming the German Nazi Party, its paramilitary and police organizations, and numerous associations subsidiary to the Nazi Party "criminal organizations". The use of similar tactics by criminal organizations for protection rackets or to enforce a code of silence is usually not labeled terrorism though these same actions may be labeled terrorism when done by a politically motivated group.
