By Raymond P. Siljander, Police Officer, Marshall, Minnesota. With a Foreword by Drake Powers. Everyone engaged in law enforcement or civil investigation will appreciate the in-depth coverage this volume gives to all aspects of physical surveillance. Novice and veteran alike will benefit from the clarity of the author's style and the authoritativeness of his presentation.
Stationary surveillance is out lined for both urban and rural settings.
Techniques of moving surveillance are presented for both foot and vehicle surveillance, using one or more operatives. The discussion of vision extenders such as telescopes, binoculars, infrared viewers and electronic light intensifiers will be of particular interest. Similar chapters are included on surveillance photography and on facts about human vision. Uniformed officers will find the section on operations while in uniform and in marked squad cars especially important. Remaining topics include methods for relocating a subject who has eluded the investigator, the need for accuracy and conciseness in reporting, and undercover surveillance.
