regulatory requirements. It does not grant police powers,
unrestricted database access, or exemption from contractual
obligations.

(BSIS) regulates private investigators and several other security-
related professions in California. Investigators must comply with
the applicable licensing and professional requirements
administered by the Bureau.

private investigative work?

Correct Answer: A. Conducting surveillance for a lawful client
purpose
Rationale: Surveillance conducted for a lawful investigative
purpose is a common private-investigation activity. Private
investigators do not possess general law-enforcement powers

confidential records.

Correct Answer: B. To determine whether the assignment is
lawful and appropriate

services are requested helps the investigator identify potential
legal, ethical, and conflicts-of-interest concerns. A professional
investigator should not knowingly undertake an unlawful
assignment.

preserve accuracy, credibility, and evidentiary value.

investigation and create avoidable legal or safety issues.

authority but no general police powers

enforcement officers. Their authority derives from applicable law,
their license, client authorization, and the circumstances of the
assignment.
