Surveillance Techniques Flashcards

Which surveillance method involves an investigator following a subject on foot through a public area?

Answer: Mobile foot surveillance

Mobile foot surveillance refers to physically following a subject on foot in public spaces to observe their movements and activities.

In a 'one-car surveillance,' what is the primary disadvantage an investigator faces?

Answer: Greater risk of detection by the subject

A single vehicle is easier for a subject to notice and identify, significantly increasing the risk of the surveillance being compromised.

What is a 'fixed surveillance' also commonly called in investigative practice?

Answer: Stakeout

A fixed surveillance, or stakeout, involves an investigator remaining stationary at a specific location to observe a subject's activities over time.

When conducting vehicle surveillance, what is the recommended following distance in urban traffic to reduce detection risk?

Answer: One to two blocks

Maintaining a distance of one to two blocks in urban settings provides enough separation to avoid detection while still keeping the subject in view.

Which of the following best describes the 'ABC method' used in mobile vehicle surveillance?

Answer: A system where three vehicles alternate lead positions

The ABC method uses three surveillance vehicles that rotate the lead position to reduce the chance of the subject recognizing a single following vehicle.

What is 'pretext surveillance'?

Answer: Using a cover story or false identity to observe a subject at close range

Pretext surveillance involves an investigator adopting a cover identity or scenario to get close to a subject without revealing their true purpose.

Which of the following is the most critical skill for an investigator to master when beginning a surveillance assignment?

Answer: Blending into the environment
