Why does the Chapter 6 reading say that, under the concept of the "Fallacy of Accuracy," using past profiles as a measure of success in predictability to assist in future profiles may not be helpful in profiling cases? This is based on the idea that the measure of success is normally based around accuracy, but this is also problematic given that profiles may be accurate, but detrimental to an investigation. Why? Chapter 9 refers to Investigative Relevance. What is investigative relevance, and why is it important? Hint: It is the extent to which characteristics in the profile actually add to the investigation. It is also the extent to which investigators can action the offender characteristics given that is crucial. Investigative relevance is important because without relevance, profiles can be damaging to the investigation by wasting time and resources
