Tactical Surveillance

tEXTBOOK - fIELD MANUAL

An Investigator's Guide

To Conducting Surveillance Operations

"Tactical Surveillance fills a void in the library of every investigator who performs surveillance."

"I recently purchased your book and have read and re-read it several times. Although I have over 35 years of experience in law enforcement, investigation and security, it is never to late for "an old dog to learn new tricks." It is without a doubt the best book that I have read on the subject of surveillance to date, and I have read a lot of them. I am always looking for ways to improve my service and "Tactical Surveillance" is a welcomed addition to my collection. If I were going to buy one book covering surveillance, yours would be the one to have".
