In addition to providing technical skills and practical advice on investigative interviewing, former police investigator Kevin Sweeney explains how to analyze information to assist in the investigation and to identify emerging trends to provide opportunities to prevent problems before they occur. Readers will come to understand legal concepts such as the chain of evidence, the psychological factors involved in questioning, and the sociological factors that can help to build a macro understanding of the organization and the event in question. This book will become an essential resource for professionals involved in auditing or investigation work of any type in the corporate or public sectors, in contexts including human resources, employee relation investigations, auditing, or where criminal activity is suspected.
