According to the Worldwide Law Enforcement Consulting Group, a training and law enforcement consulting organization, an investigation is “an examination, a study, a survey and a research of facts and/ or circumstances, situations, incidents and scenarios, either related or not, for the purpose of rendering a conclusion of proof” (Fundamentals of criminal investigation, 2015). When a police officer investigates, he or she makes a systematic inquiry, closely analyzes, and inspects while dissecting and scrutinizing information.
Later in this book, we will look at how important it is for both civilian intelligence analysts and tactical analysts to have a basic understanding of the process of criminal investigations. This can help the analyst develop an investigative mindset that can lead to better and more relevant intelligence provided to criminal investigators. For now, however, let us look at the investigative process as it relates to the police and how they investigate crimes and suspicious events.
