The Fourth Amendment's reasonable expectation of privacy standard, established in Katz v. United States, determines whether surveillance constitutes a legal search.

A CLI investigator conducting mobile surveillance observes the subject enter a private residence. What is the correct action?

Answer: Use zoom equipment from a public vantage point

Investigators must remain in public areas and may use zoom or telephoto equipment to observe subjects without trespassing on private property.

When conducting stationary surveillance, what is the primary purpose of a 'cover story'?

Answer: To provide a plausible innocent explanation for the investigator's presence

A cover story gives the investigator a believable reason for being in a location without revealing the nature of the investigation to third parties.

Which type of surveillance log entry is most critical for maintaining the evidentiary value of surveillance documentation?
