The experience of many authorities in handling crises is that however well the underlying physical and technical issues are addressed, the potential for losing public confidence in the process is considerable. One means of addressing this dislocation between the authorities and the publics they serve is to establish mechanisms for communication, discussion and engagement before, during and after any incident. Such methods are currently being ported to web-based interactions. Engagement with the public may also identify potential consequences that the authorities might otherwise overlook. In the recovery phase, interaction with the public and particular stakeholders through various participatory instruments may lead to better received and more legitimate remedial actions.
