The exercise of due diligence and the exercise of caution and care is the process of investigating in accord with generally recognized standards and procedures. The measure is whether another investigator-when faced with the same facts and circumstances-would have made the same decisions. A failure of due diligence may result from negligence, indifference, or it may occur by intent through malfeasance. It may occur within a single aspect of an investigation, such as failure to follow a lead, or it may permeate an investigation entirely when an investigation is treated with indifference from the onset. The result is an incomplete investigation due to flawed theories, leads not followed or evidence misunderstood in the context of the crime. Analysis for due diligence is comprehensive, beginning with the crime scene and moving forward in a thorough, methodical process. Analysis will identify the issues. It can exonerate the wrongfully accused. In some instances, it may identify the guilty.
