Additionally, the book provides good tuition on PERSONAL SECURITY, something which no one should underrate or brush aside even if one has paid security details providing such services 24/7. Remember, it’s PERSONAL SECURITY and not SECURITY BY ANOTHER PERSON.  The best person to trust is one’s own self in security matters.  If the security guard turns his neck around, how  do you put him in check if you have no idea yourself.  Note that guns and gadgets are never enough to secure one’s life in terms of “PREVENTIVE” SECURITY.  Learn more from “PROFESSIONAL INVESTIGATION” by E. Anim-Danquah and protect yourself and your family.   The book is further recommended to professionals like judges/magistrates, journalists, businessmen especially those who own large businesses, legal practitioners and private security organizations.

A primer offers basic principles of investigation.

Anim-Danquah (Principles of Interrogation, 2013) cautions readers that since the stakes are so high, an investigator can never be too meticulous. His brief but comprehensive survey is broadly conceived to cover “training material for all levels in all Security Services and Intelligence Agencies but equally a very good source of reference after formal training or during professional practice.” The author proceeds systematically, discussing the chief elements of the various kinds of investigation, the basic considerations of interrogation, and the types of evidence and the methods of gathering it. In addition, he analyzes in considerable detail the kinds of modus operandi: 23 different factors that in their totality define any “particular criminal activity or offence.” He devotes an unusual amount of attention to the filling out of reports and the distinction between various types, and he includes samples. This is especially peculiar since the author’s explanatory scope is so broad—it can’t possibly be the case that every investigator in every jurisdiction is confronted with the same forms. Equally puzzling is his protracted assessment of the various distractions that could stymie a successful investigation; for example, he warns against the deflection of one’s attention that could be caused by offensive odors. The book concludes with a series of helpful illustrative case studies that feature instructional questions. Anim-Danquah worked in investigations and intelligence for the government of Ghana for more than 20 years, and his thoroughness and rigor are clear expressions of that expertise. His primer is best used as a reference source—an encyclopedic catalog of all the basic ingredients of investigation, very generally understood. But it’s not an instructional guide in the sense of providing much actionable counsel—readers will learn much more about the various categories of evidence than its professional collection. In addition, the author too often dwells on points so common-sensical as to be banal. For example, it seems unnecessary to insist that aspiring investigators check their spelling on the reports they file.

An exhaustive account of investigation principles, more academic in conception than immediately practical.

Professional Investigation by Emmanuel Anim-Danquah is an eye-opening book on the principles of investigation, a comprehensive book that details the step-by-step rules to follow in an investigation, what to know and how to successfully conduct and complete an investigation. The author talks about the importance of planning, of considering funding and logistics, of the taboos involved and the legal steps that eventually lead to the truth. Readers will understand the kind of evidence deemed admissible in court, how to acquire such evidence, and how to craft reports that are acceptable in civil and criminal cases. The book explores the different moments of the investigation, including admissible and inadmissible evidence, arrests, interrogation, searches, statements, arrests and a lot more.

This is a book that investigators and rookies need to read, a reference book that will help any investigator and police officer do their work better. Professional Investigation by Emmanuel Anim-Danquah is well-researched and the author provides material that readers need to know. I never knew that an investigation required so much and that the rules were so many and this book didn’t just inform but explained why many hard pieces of evidence are denied in a court of law. In the introduction, the author explains why it is important that the investigation is done right and thoroughly, and makes a very troubling statement: “Professionalism is key in the conduct of investigation. Wrong arrests, wrong reports, delayed reports, shelving, and censuring of vital evidence leading to misleading judgments in prosecution, wrong decision making in policy formulation and so on are very grave concerns in investigation.” This book provides need-to-know information to the general reader, tips to investigators, and the place that professional investigation has in the pursuit of justice. It is a vade-me-cum for anyone who is desirous of justice and who wants to understand the mechanics of successful investigations. Professional
Investigation is well-researched, professionally written and packed with interesting information.
