CLI Surveillance & Fieldwork Techniques Flashcards

What is 'pretext' as used in legal investigation fieldwork?

Answer: A false identity or scenario used to gather information

Pretext involves assuming a false identity or creating a fictional scenario to induce a subject or third party to reveal information they might otherwise withhold.

In most US states, using pretext to impersonate a law enforcement officer during an investigation is:

Answer: A criminal offense

Impersonating a law enforcement officer is a criminal offense in all US states, regardless of licensure or client disclosure.

What photographic practice best preserves the evidentiary chain for surveillance photos taken in the field?

Answer: Using camera metadata (EXIF data) with date/time stamps and maintaining unedited originals

Preserving unedited originals with intact EXIF metadata establishes authenticity and supports chain of custody, making photos admissible in court.

Which surveillance technique involves following a subject through multiple vehicles or personnel to avoid detection?

Answer: Leapfrog surveillance

Leapfrog surveillance uses multiple vehicles or operatives who alternate positions and roles to maintain coverage of a moving subject while reducing detection risk.

A CLI investigator notices the subject appears to have identified the surveillance. What is the recommended immediate action?

Answer: Terminate surveillance and regroup to avoid compromising the investigation

Terminating surveillance when burned prevents escalation, protects evidence already gathered, and preserves the ability to resume later under better conditions.

What is the legal significance of the 'open fields' doctrine in surveillance operations?

Answer: Areas beyond the curtilage of a home generally lack Fourth Amendment protection

Under the open fields doctrine from Hester v. United States, areas beyond the immediate surroundings of a home (curtilage) typically do not carry Fourth Amendment privacy protections.
