Mandate, surveillance and undercover work: key rules to remember

Principles of surveillance ("generally accepted practices throughout the private investigation industry")

  • Covert surveillance observes persons, places or things without being detected, to see the subject in their natural state; results are usually video or photographs, which are illustrative evidence.
  • Purposes include locating people, documenting activities or health status, locating hidden or stolen property, preventing or catching an act, preparing for an interview, and obtaining court evidence.
  • Before starting, gather the subject's name, date of birth, address, phone numbers, employment, places frequented and the purpose of the surveillance; check the file or office if anything is missing.
  • Obey all laws while following a subject, including traffic laws, even if the subject speeds or runs a light.
  • If the subject is represented by a lawyer, general practice is to avoid verbal contact with the subject.
  • Standard equipment: a nondescript vehicle in a muted colour, a video camera with night capability, a still camera with zoom, notepads, binoculars, a change of clothes, money, two-way radio and a recorder for notes.
  • Watch for signs the surveillance is compromised, balancing "paranoia" against real indicators.
  • Most surveillance is done alone; teams are used for aggressive drivers, multiple exits or counter-surveillance, and allow caravan, leapfrog and parallel methods; team members stay in constant communication.

Locating and mandate

  • Before taking a case, establish a justifiable mandate with the client: what is requested, why, whether it is frivolous, and whether obtaining it is lawful; document the reason; sometimes check the client's claims and background.
  • Double-check the accuracy of information supplied; use public databases, internet sources and libraries; a newspaper advertisement is a last resort for finding a missing person.

Undercover operations

  • Undercover work is a last resort; often used for workplace issues such as employee theft.
  • The operator is briefed on the environment, supervisors, suspects, infractions sought, job expectations and where suspects gather; a supervisor debriefs them in person after each shift and receives evidence.
  • Operators report all infractions seen, keep their credibility (no drugs or alcohol, no offering money to steal), and must not encourage or assist any contravention; they must not record conversations they are not part of; no cameras in washrooms.
  • It is generally the client's decision whether to inform police.
