Enforcing social morals by banding a group of citizens together to capture, examine and judge in summary fashion, and punish transgressors of law or morality.
Implementation:
Due to an upsurge in crime, the owners of 20 bars in central Vienna, Austria, legally hired, in 1994, a firm of gun-carrying private detectives in military-style uniforms accompanied by rotweiler dogs, to patrol the streets at night to maintain law and order. The New York-based "Guardian Angels" organization has established groups in Britain, Germany, and Sweden. They carry out safety patrols on public transport.
Counter Claim:
1. Vigilantism leads to the breakdown of law and civil order.
2. The natural outcome of vigilantism is that the strongest person or persons define social morals, resulting in a dictatorship.
