Interviews, statements and reports: key rules to remember

Our summary of what the official handbook says on this topic, in our own words. Read it before or after the practice questions above, then check the original chapter. Read the official chapter ↗

Interview techniques (general practice)

  • Know the purpose of the interview; prepare questions, notebook, pens and a recorder.
  • Never record a conversation without the knowledge and consent of one of the parties; recording others' conversation without consent is a criminal offence (Criminal Code s. 184).
  • Make an appointment with a co-operative witness; a cold call may suit some cases; state your business truthfully without revealing confidential information.
  • Identify yourself and show your licence; do not interrupt once the person talks; take notes discreetly; control your emotions; close courteously.
  • Write the investigative report immediately after the interview.

Statements

  • Purpose: an accurate record of the witness's recollection.
  • Include the witness's full name, date of birth, ID, employment and contact information, address, location, date, start and end times, the investigator's name and company, an introduction, a verbatim account and a closing paragraph.
  • Let the witness review and change the statement before signing; strike through changes with both sets of initials; initial or sign each page; draw an X through unused space on the last page.
  • Record that the information was given of the witness's own free will; a confession must involve no threat or promise, or it will be inadmissible.

Report writing and reports as evidence

  • Reports are objective and standardized: date, time, location, actions, descriptions, observations, time of completion.
  • Record notes as soon as possible; a recorder helps but can fail; add omitted information when remembered; correct errors by a single line and initials.
  • Final reports come from personal notes and a review of the video; surveillance reports start with the subject's name, file number, date and time.
  • In court, with permission, notes may be used as a memory aid only; review them before testifying.

Making a statement (March 12, 2026)

  • Police ask witnesses for exact time and location, names, descriptions (hair, build, height, sex, race), what was seen, and vehicle plate, colour and type; read a statement fully and sign only if accurate.
