More importantly, it is obviously the case that for a crime to appear in published Garda statistics, it must first be reported to the Garda Síochána. It is a fact, however, that members of the general public take a very selective approach in deciding whether to report incidents of criminal victimisation. For example, in the survey on crime and victimisation carried out by the Central Statistics Office in 1998 as part of the quarterly national household survey, the percentage of crimes reported to the Garda Síochána varied between a high of 94.9% in relation to the theft of a vehicle to a low of 39.6% in the case of vandalism. In the CSO survey, the main reason cited for non-reporting was a perception that the incident was not serious enough or did not result in loss. This was often followed by the view that the Garda Síochána could effectively do nothing about it due to a lack of proof, given the nature of the circumstances.
