A WIDE VARIETY OF TYPES OF SURVEILLANCE IS REVIEWED WITH AN INDICATION OF WHAT IS INVOLVED IN EACH AND UNDER WHAT CONDITIONS EACH IS APPLICABLE. STATIONARY SURVEILLANCE OR STAKE-OUTS ARE DISCUSSED FOR BOTH URBAN AND RURAL SETTINGS. SOME OF THE MORE EFFECTIVE VANTAGE POINTS ARE INTRODUCED AND THE USE OF PRETEXTS FOR BEING IN A GIVEN AREA FOR VARYING AMOUNTS OF TIME IS OUTLINED. THE TEXT EXPLAINS METHODS AND TECHNIQUES OF MOVING SURVEILLANCE, INCLUDING FOOT AND VEHICLE SURVEILLANCE WITH ONE OR MORE OPERATIVES. POSSIBLE PITFALLS ARE DELINEATED, ALONG WITH EVASIVE ACTIONS WHICH THE SUBJECT MAY USE IF HE SUSPECTS THAT HE IS BEING SURVEILLED. COUNTERMEASURES WHICH THE INVESTIGATOR MAY EMPLOY IN THE FACE OF SUCH EVASIVE ACTIONS ARE DISCUSSED. CHAPTERS COVER VISION EXTENDERS AND PHOTOGRAPHIC EQUIPMENT, INCLUDING ILLUSTRATIONS OF THE DEVICES AND THEIR APPLICABILITY TO SURVEILLANCE OPERATIONS. A SPECIAL SECTION DISCUSSES UNIQUE SURVEILLLANCE REQUIREMENTS FOR UNIFORMED OFFICERS WHILE ON A NORMAL TOUR OF DUTY. OTHER TOPICS INCLUDE METHODS FOR RELOCATING A SUBJECT WHO HAS ELUDED THE INVESTIGATOR, THE NEED FOR ACCURACY AND CONCISENESS IN REPORTING, AND UNDERCOVER SURVEILLANCE. THE LATTER PRESENTS DISCUSSIONS OF PRETEXTS AND OF LEGAL CONSIDERATIONS. AN INDEX IS INCLUDED. (AUTHOR ABSTRACT MODIFIED).
