Introduction to Criminal Investigation, Processes, Practices, and Thinking is a teaching text designed to assist the student in developing their own structured mental map of processes, practices, and thinking to conduct criminal investigations. Delineating criminal investigation into operational descriptors of tactical-response and strategic response while using illustrations of task-skills and thinking-skills, the reader is guided into structured thinking practices. Using the graphic tools of a “Response Transition Matrix”, an “Investigative Funnel”, and the “STAIR Tool”, the reader is shown how to form their own mental map of investigative thinking that can later be articulated in support of forming their reasonable grounds to believe. Chapter 1 introduces criminal investigation as both a task process and a thinking process. This chapter outlines these concepts, rules, and processes with the goal of providing practical tools to ensure successful investigative processes and practices. Most importantly, this book informs the reader how to approach the investigative process using “investigative thinking.” Chapter 2 illustrates investigation by establishing an understanding of the operational forum in which it occurs. That forum is the criminal justice system and in particular, the court system. The investigative process exists within the statutory rules of law, including the Canadian Charter of Rights and Freedoms, and case law rulings adjudicated by the courts. Considering the existence of these conditions, obligations, and case law rules, there are many terms and concepts that an investigator needs to understand to function appropriately and effectively within the criminal justice system. The purpose of this chapter is to introduce some of the basic legal parameters and concepts of criminal justice within which the criminal investigation process takes place. Chapter 3 describes the functions and terms of “evidence”, as they relate to investigation. This speaks to a wide range of information sources that might eventually inform the court to prove or disprove points at issue before the trier of fact. Sources of evidence can include anything from the observations of witnesses to the examination and analysis of physical objects. It can even include the spatial relationships between people, places, and objects within the timeline of events. From the various forms of evidence, the court can draw inferences and reach conclusions to determine if a charge has been proven beyond a reasonable doubt. Considering the critical nature of evidence within the court system, there are a wide variety of definitions and protocols that have evolved to direct the way evidence is defined for consideration by the court. In this chapter, we look at some of the key definitions and protocols that an investigator should understand to carry out the investigative process. Chapter 4 breaks investigation down into logical steps, establishing a progression that can be followed and repeated to reach the desired results. The process of investigation can be effectively explained and learned in this manner. In this chapter the reader is introduced to various issues in the progression that relate to the process of investigation. Chapter 5 examines the operational processes of investigation. In this chapter we introduce the three big investigative errors along with graphic illustrations of “The Investigative Funnel” and the “S T A I R Tool” to illustrate how each of these concepts in the investigative progression. Chapter 6 provides the reader the opportunity to work through some investigative scenarios using the S T A I R Tool. These scenarios demonstrate the investigative awareness required to transition from the tactical investigative response to the strategic investigative response. Once in the strategic response mode the reader is challenged to practice applying theory development to conduct analysis of the evidence and information to create an investigative plan. This chapter presents two investigative scenarios each designed to illustrate different steps of the S T A I R tool allowing the student to recognize both the tactical and the strategic investigative responses and the implications of transitioning from the tactical to the strategic response. Chapter 7 illustrates the investigative practices of witness management. Witness statements will assist the investigator in forming reasonable grounds to lay a charge, and will assist the court in reaching a decision that the charge against an accused person has been proved beyond a reasonable doubt. It is important for an investigator to understand these practices as they allow an investigator to evaluate witnesses and collect witness evidence that will be acceptable to the courts. Chapter 8 describes crime scene management skills. These skills are an extremely significant task component of investigation because evidence that originates at the crime scene will provide a picture of events for the court to consider in its deliberations. That picture will be composed of witness testimony, crime scene photographs, physical exhibits, and the analysis of those exhibits, along with the analysis of the crime scene itself. From this chapter, the reader will learn the task processes and protocols for several important issues in crime scene management. Chapter 9 examines the interviewing, questioning, and interrogation techniques police use to aid them in investigations. The courts expect police to exercise high standards using practices that focus on the rights of the accused person, and minimize any physical or mental anguish that might cause a false confession. In meeting these expectations, the challenges of suspect questioning and interrogation can be complex, and many police agencies have trained interrogators and polygraph operators who undertake the interrogation of suspects for major criminal cases. But not every investigation qualifies as a major case, and frontline police investigators are challenged to undertake the tasks of interviewing, questioning, and interrogating possible suspects daily. The challenge for police is that the questioning of a suspect and the subsequent confession can be compromised by flawed interviewing, questioning, or interrogation practices. Understanding the correct processes and the legal parameters can make the difference between having a suspect's confession accepted as evidence by the court or not. Chapter 10 examines various forensic sciences and the application of forensic sciences as practical tools to assist police in conducting investigations. As we noted in Chapter 1, it is not necessary for an investigator to be an expert in any of the forensic sciences; however, it is important to have a sound understanding of forensic tools to call upon appropriate experts to deploy the correct tools when required. Chapter 11 summarizes the learning objectives of this text and suggests investigative learning topics for the reader going forward. Many topics relative to investigative practices have not been covered here as part of the core knowledge requirements for a new investigator. These topics include: Major Case ManagementInformant and confidential source managementUndercover investigationsSpecialized team investigations

This book is intended for the Risk Management and Insurance course where Risk Management is emphasized. When we think of large risks, we often think in terms of natural hazards such as hurricanes, earthquakes or tornados. Perhaps man-made disasters come to mind such as the terrorist attacks in the U.S. on September 11, 2001. Typically we have overlooked financial crises, such as the credit crisis of 2008. However, these types of man-made disasters have the potential to devastate the global marketplace. Losses in multiple trillions of dollars and in much human suffering and insecurity are already being totaled, and the global financial markets are collapsing as never before seen. We can attribute the 2008 collapse to financially risky behavior of a magnitude never before experienced. The 2008 U.S. credit markets were a financial house of cards. A basic lack of risk management (and regulators' inattention or inability to control these overt failures) lay at the heart of the global credit crisis. This crisis started with lack of improperly underwritten mortgages and excessive debt. Companies depend on loans and lines of credit to conduct their routine business. If such credit lines dry up, production slows down and brings the global economy to the brink of deep recession—or even depression. The snowballing effect of this failure to manage the risk associated with providing mortgage loans to unqualified home buyers have been profound, indeed. When the mortgages failed because of greater risk- taking on the Street, the entire house of cards collapsed. Probably no other risk-related event has had, and will continue to have, as profound an impact world wide as this risk management failure. How was risk in this situation so badly managed? What could firms and individuals have done to protect themselves? How can government measure such risks (beforehand) to regulate and control them? These and other questions come to mind when we contemplate the consequences of this risk management fiasco. Standard risk management practice would have identified sub-prime mortgages and their bundling into mortgage-backed-securities as high risk. People would have avoided these investments or would have put enough money into reserve to be able to withstand defaults. This did not happen. Accordingly, this book may represent one of the most critical topics of study that the student of the 21st century could ever undertake. Risk management will be a major focal point of business and societal decision—making in the 21st century. A separate focused field of study, it draws on core knowledge bases from law, engineering, finance, economics, medicine, psychology, accounting, mathematics, statistics and other fields to create a holistic decision-making framework that is sustainable and value- enhancing. This is the subject of this book.
