It is necessary for people to understand the extent of criminal activity in order for them to coordinate an effective response  People have a right to know, for the sake of their own safety, about violent crimes being committed. Otherwise they will be unable to prepare themselves adequately for the possibility of being attacked. However people cannot make rational decisions about how to react and respond to violence in society if they do not have an accurate picture of not only the frequency of crime, but also their nature. Everyone should take necessary precautions to prevent themselves being victims of crime, as part of this they should know what areas are for example safe to walk through at night. If there is little or no reporting of where and when crime occurs the public will not have this necessary knowledge to keep themselves safe. Local groups will also be less able to protect their neighborhoods. For example in Pimlico, London, local groups have set up patrols in order to deal with an increase in muggings, if these muggings were not reported such local action would not have been possible.
