From a law enforcement perspective, the investigative technique known as surveillance

involves visual observation of a person or targeted location by law enforcement person-

nel for the purpose of developing information that can ultimately lead to prosecution.

Surveillance is a basic investigative technique that probably dates to law enforcement’s

earliest days. Modern technology has given law enforcement many tools to enhance sur-

veillance; however, the technique continues to consist mainly of personal observations

of people and locations by investigators. (It is noted that the term surveillance could also

include technical coverage of a subject or location. For purposes of this text, this form of

coverage is treated in Chapter 19, Technical Investigative Techniques.)
