Large events of all kinds can lead to disruptions of the normal operation of a public authority
or company. Such events include street festivals, concerts, sporting events, labour disputes,
and demonstrations. Rioting in connection with such events can have additional side-effects
ranging from intimidation of the organisation's personnel to the use of violence against
personnel or the building.
Examples:
• During the hot summer months, a demonstration was held in the vicinity of a
computer centre. The situation escalated and led to violence. One window of the
computer centre facing a side street was left open. A demonstrator entered through the
window and took the opportunity to steal hardware which contained important
information.
• An electrical power line was cut accidentally while setting up a large funfair. This lead
to a power failure in the computer centre supplied with power by this line, although
the centre's emergency power system was able to take over and provide power.
