67-72). This is data recorded by emergency services such as ambulances, firefighters or hospital emergency departments (HRC 2004, pp. 67-72). A significant concern with this type of data is that it only records statistics regarding a small selection of crimes due to the nature of the crime (Morgan & Clare 2012, pp 25-52). For example, crash data mostly report drink driving offenses due to the greater propensity of a drink driver to be involved in a collision (Morgan & Clare 2012, pp 25-52). Whereas hospital emergency rooms predominantly report crimes involving illicit drugs, as many of those who purchase and use illicit substances are more likely to seek medical attention for adverse effects or overdoses (Morgan & Clare 2012, pp 25-52). This not only significantly diminishes the criminologist's ability to collect statistics on a variety of criminal crimes, but also has questionable reliability due to the fact that many of the crimes do not require emergency and emergency services and therefore go unreported. Similarly, the subjectivity of crime definitions is also a further disadvantage to this method (AIC 2012 and Morgan & Clare 2012, pp 25-52). The different way in which emergency services officers classify events or incidents into crime types plays an important role in the statistical representation of crime (Morgan & Clare 2012, pp 25-52).
