All 14 questions in this test
Every question and its answer choices. The correct answers and explanations appear when you take the test above.
You are testifying about a surveillance file. How may you use your notes on the witness stand?
- With the court's permission, as a memory aid
- Hand them to the judge instead of testifying
- Read them aloud word for word without asking
- Not at all, because notes are always hearsay
Before signing, a witness asks to remove a sentence from her statement. How is the change made?
- Strike a line through it; both of you initial the start and end
- Leave it in and add a note on the last page
- Use correction fluid on the sentence and have only the witness initial it
- Rewrite the whole page and destroy the original
How should the witness's account of events be written in a statement?
- Verbatim, word for word as the witness tells it
- Summarized in the investigator's own words
- Rewritten in legal terms for the court
- Shortened to the points that help the client
When should you write your investigative report after an interview?
- Immediately after the interview
- After the case goes to court
- At the end of the week with other reports
- Only if the client asks for one
At the start of an interview with a witness, what should you do?
- Start recording secretly before saying who you are

Reviewing your notes, you find a wrong licence plate number. How do you correct it?

Once a witness starts talking freely, what is the recommended practice?

You need a statement from a 16-year-old witness. What is industry practice?
- Wait until the youth turns 18 before taking a statement

Interviews, statements and reports: key rules to remember

Interview techniques
- Good sources include former spouses, relatives, neighbours, business competitors, employees, employers, business associates and landlords.
- The key to a successful interview is knowing its purpose.
- Be prepared: review what you know, prepare questions, bring notebook, pens, recorder, enough tapes and new batteries.
- Make an appointment when the witness is expected to cooperate; a "cold call" may be better in some cases. State your business truthfully without revealing confidential information.
- At the start, greet the person, identify yourself and show your PI licence; formal or informal approach depending on the person.
- Once the person talks, do not interrupt; take notes discreetly; control your emotions and never react.
- End courteously so future cooperation is likely; write the investigative report immediately after.
- Syllabus: interviewing differs from interrogating; narrative vs cognitive and civil vs criminal interviews; assess credibility, reliability and suitability of a witness.
Statements
- Purpose of a statement: an accurate record of the witness's recollection of an event.
- Typical content: witness's full name, date of birth, ID, employment, contact information and address, place and date of the interview, start and finish times, the PI's name and company, an introduction, the witness's account word for word (verbatim), and a closing paragraph.
- The closing paragraph confirms the witness read the statement, finds it accurate and was told they could change any part before signing.
- Changes: draw a line through the removed item; the witness and the PI initial at the start and end of the correction.
- Initial or sign every page; after the signatures on the last page, draw an "x" through the rest of the page.
- A prepared questionnaire can keep a wandering witness on track.
- Record that the witness gave the information of their own free will.
- If the statement may be a confession, make no threat and no promise of immunity; coerced confessions are inadmissible.
- Lawyers may cross-examine every witness at trial, so statements must reflect the truth.
- For a youth under 18, industry practice is to get permission from a parent or legal guardian and let them be present.
- The study guide says the most important things to document are the value, credibility and honesty of the information, and refers to the Ibrahim rule (a statement must be free of duress to be admissible).
Report writing
- Reports must be objective and standardized; types include legal and insurance reports; reports can be used for audits or as evidence.
- Basic elements: date, time, location, actions/behaviours, descriptions of people, observations, time of completion.
- Record notes and observations as soon as possible; a digital recorder can help but should not be relied on alone (batteries, malfunctions).
- If a critical detail was left out, add it when you remember it; for an error, draw a line through it and initial it.
- Write the final report from personal notes and review any video to check accuracy.
- A standard surveillance report starts with the subject's name, file number, date and time, and other details per company policy (weather, video equipment, neighbourhood).
- Syllabus: an objective report sticks to facts, is written in the third person, avoids emotional terms and introspection, and is clear and concise.
Reports as evidence
- A PI may receive a subpoena and testify; thorough, accurate notes are essential.
- On the stand the PI may refer to notes only with the court's permission; notes are a memory aid, not something to read from.
- Before court, review all notes carefully.
