Private detectives and investigators also conduct surveillance when working on a case. They may keep watch through binoculars or take photographs, often from a hidden position, to gather information on people of interest.
Private detectives and investigators must obey the law when conducting investigations. Because they lack police authority, they are held to the same standards of conduct as private citizens. As a result, these workers must have a thorough understanding of federal, state, and local laws, such as privacy laws, that may affect their work. Lawful collection of evidence ensures its usability in court and protects detectives and investigators from prosecution.
Skip tracers specialize in locating people whose whereabouts are unknown. For example, debt collectors may employ skip tracers to locate people who have unpaid bills.
Store detectives, or loss prevention associates, typically work undercover to identify and prevent shoplifting or theft. These plainclothes detectives may pretend to be customers as they walk through the store observing other shoppers.
