Civil disorder, also known as civil unrest or civil strife, is a broad term that is typically used by law enforcement to describe unrest caused by a group of people. Civil disturbance can include a form of protest against major socio-political problems, but also can simply be an expression of antisocial values. It is essentially the breakdown of orderly society, of which examples can include: illegal parades; sit-ins and other forms of obstructions; riots; sabotage; and other forms of crime. Even on occasions where it is typically intended to be a demonstration to the public or the government, such can escalate into general chaos.
