Civil disorder is a broad term that typically is used by law enforcement to describe forms of disturbance when many people are involved and are set upon a common aim. Civil disorder has many causes, including large-scale criminal conspiracy, socio-economic factors (unemployment, poverty), hostility between racial and ethnic groups, and outrage over perceived moral and legal transgressions. Examples of well-known civil disorders and riots are the poll tax riots in the United Kingdom in 1990; the 1992 Los Angeles riots in which 53 people died; the 2008 Greek riots after a 15-year-old boy was fatally shot by police; and the 2010 Thai political protests in Bangkok during which 91 people died. Such behavior is only hazardous for those directly involved as participants, those controlling the disturbance, or those indirectly involved as passers-by or shopkeepers for example. For the great majority, staying out of the way of the disturbance avoids the hazard.
