The intent and perspective of this book remain effectively outlined in the initial paragraphs of the preface to the first edition. However, in creating the second edition, the author was motivated by the surprising success of the first edition, which, although primarily intended for non-scientists involved in law enforcement, proved to be more effective than anticipated as an introduction to forensic science for aspiring professionals. Consequently, in this edition, the author has endeavored to balance a comprehensive and scientifically sound exploration of the subject with accessible explanations geared towards readers lacking a scientific background. The degree of success in achieving this balance is open to evaluation by others.
