7.1 Objective vs. Subjective Language & Professional Police Report Writing
Key Takeaways
- Under the landmark Supreme Court of Canada ruling R. v. Stinchcombe (1991), police occurrence reports and duty notebook entries are subject to full Crown and defense disclosure as primary evidence in criminal proceedings.
- Objective report writing documents observable, empirical sensory facts (visual observations, auditory statements, physical measurements) rather than subjective inferences, personal opinions, emotional editorializing, or speculative motives.
- Active voice ('Constable Tremblay searched the vehicle and seized the weapon') establishes clear officer accountability and chronological sequence, whereas passive voice ('The vehicle was searched and the weapon was seized') obscures officer actions.
- Operational narratives must eliminate police slang, street colloquialisms, and radio 10-codes (e.g., 10-4, 10-23, 10-15), translating all events into standard, professional plain English.
- Investigative narratives are structured around the 5 Ws and 1 H (Who, What, When, Where, Why, and How), utilizing verbatim direct quotes inside quotation marks for admissions, threats, and spontaneous utterances.
7.1 Objective vs. Subjective Language & Professional Police Report Writing
Executive Summary: On the Alberta Police Cognitive Ability Test (APCAT), the Written Communication component rigorously evaluates your mastery of objective reporting, grammatical precision, and standard syntax. Frontline police reports are not private internal records; they are foundational legal documents disclosed in criminal trials, subject to intense cross-examination by defense counsel and judicial scrutiny. This section establishes the legal, linguistic, and operational standards required to construct objective, airtight occurrence narratives.
The Constitutional & Evidentiary Framework (R. v. Stinchcombe)
In Canadian criminal law, police report writing is governed by the constitutional disclosure standard established by the Supreme Court of Canada in the landmark decision R. v. Stinchcombe [1991] 3 S.C.R. 326. Under Stinchcombe, the Crown has an absolute legal duty to disclose all non-privileged, relevant information gathered during a police investigation to the defense, whether that evidence is inculpatory (inculpating the accused) or exculpatory (favourable to the accused).

└─────────────────────────────────────────────────────────────────────────┘
Because your occurrence narrative, supplementary statements, and duty notebook entries will be read verbatim in court, vague wording, subjective conjecture, or sloppy grammar can fatally compromise a prosecution, lead to the exclusion of critical evidence under Section 24(2) of the Charter of Rights and Freedoms, or undermine your professional credibility on the witness stand.
Objective Sensory Observations vs. Subjective Editorializing
The fundamental cornerstone of professional police documentation is the strict separation of Objective Sensory Facts from Subjective Inferences, Assumptions, and Editorial Commentary.
- Objective Language: Describes verifiable physical facts gathered directly through the five human senses (sight, hearing, smell, touch, and taste) or scientific instruments. It records what actually happened without emotional bias or mind-reading.
- Subjective Language: Expresses personal opinions, emotional impressions, speculative motivations, medical or psychiatric diagnoses without credentials, or value-laden adjectives that cannot be independently measured.

└──────────────────────────┴──────────────────────────────────────────────┘
Rules for Objective Documentation
- Record the Specific Stimulus, Not the Label: Instead of writing "The male was intoxicated," document "The male had slurred speech, glossy bloodshot eyes, and an unsteady gait."
- Avoid Mind-Reading and Intent Attribution: Instead of writing "The suspect tried to deceive police," document "The suspect stated his name was John Doe, but his Alberta driver's licence identified him as Richard Roe."
- Quantify and Specify: Replace vague qualifiers ("a large amount of cash," "a massive knife") with precise measurements ("$4,520 in Canadian currency consisting of forty-five $100 bills and one $20 bill," "a fixed-blade hunting knife with a 15-centimetre serrated steel blade").
Active Voice vs. Passive Voice for Officer Accountability
In standard English composition, sentences can be structured in either active or passive voice. In law enforcement documentation, active voice is mandatory because it establishes unambiguous personal accountability for every operational action.
┌─────────────────────────────────────────────────────────────────────────┐
│ ACTIVE VERSUS PASSIVE SYNTAX │
├─────────────────────────────────────────────────────────────────────────┤
│ ACTIVE VOICE (MANDATORY): │
│ [Subject / Actor] + [Active Verb] + [Direct Object] │
│ Constable Tremblay searched the suspect's backpack. │
│ (Clear: Exactly who conducted the search is explicitly stated) │
├─────────────────────────────────────────────────────────────────────────┤
│ PASSIVE VOICE (UNACCEPTABLE IN POLICE NARRATIVES): │
│ [Direct Object] + [Passive Verb Phrase] (+ Optional Actor) │
│ The backpack was searched (by police). │
│ (Ambiguous: Who searched the bag? Was it lawful? Who found the drugs?)│
└─────────────────────────────────────────────────────────────────────────┘
Why Passive Voice Damages Court Cases
When an officer writes "The knife was located under the driver's seat and the suspect was arrested," defense counsel will exploit the syntactic ambiguity during cross-examination:
- "Officer, your report says the knife was located. Did you locate it, or did your partner? Did you touch it? Who seized it? If you didn't write your name, how do we know the chain of custody?"
| Passive Construction (Avoid) | Active Construction (Court-Ready) |
|---|---|
| The front door was forced open. | Constable Vance forced open the front door using a manual pry tool. |
| The Charter warning was read to the accused. | Constable Zhao read the Charter warning and official caution to the accused from her issued duty card. |
| Three spent 9mm shell casings were recovered. | Detective Miller photographed and seized three spent 9mm shell casings from the sidewalk. |
| The suspect was instructed to exit the vehicle. | Constable Lee instructed the suspect to exit the vehicle. |
Elimination of Police Slang, Radio 10-Codes, and Jargon
Radio 10-codes and informal police vernacular are operational shortcuts designed for rapid two-way radio dispatch. They have no place in formal occurrence narratives, sworn affidavits, or Crown disclosure packages.

Core Rule: Judges, jurors, and defense attorneys are civilian participants in the justice system. Using codes like "Unit 12 went 10-23 at the 10-20 and took the male 10-15" degrades professionalism and introduces legal ambiguity into official trial transcripts.
The 5 Ws and 1 H in Incident Structure
Every complete police occurrence narrative must systematically answer six foundational investigative questions:
- Who: Identify all parties with full legal names, dates of birth, contact details, and operational roles (Complainant, Victim, Witness, Accused, Assisting Constable, Primary Investigator).
- What: Specify the exact nature of the occurrence, the statutory offenses investigated, physical actions taken, evidence collected, and injuries sustained.
- When: Record precise 24-hour timestamps (e.g., "At 2145 hours, dispatch broadcast... At 2152 hours, Constable Chen arrived...").
- Where: Document the exact geographic location, including municipal quadrant, building type, specific room, and physical lighting/weather conditions (e.g., "Inside the master bedroom of 1420 8th Avenue NW, Calgary, AB").
- Why: Articulate the legal grounds, statutory elements of intent (mens rea), or spontaneous motive statements provided by the accused. (Never invent or speculate on why someone acted; document only stated or evidential reasons).
- How: Describe the mechanics of the event—how entry was gained, how the weapon was deployed, how the vehicle was operated, and how officers gained physical control.
Verbatim Direct Quotes vs. Indirect Attribution
When transcribing verbal statements, admissions, threats, or spontaneous utterances (res gestae), officers must distinguish between direct quotations and indirect summaries.
┌─────────────────────────────────────────────────────────────────────────┐
│ SPEECH TRANSCRIPTION PROTOCOLS │
├─────────────────────────────────────────────────────────────────────────┤
│ DIRECT QUOTATION (VERBATIM): │
│ • Captures the exact, word-for-word spoken utterance inside quotation │
│ marks, preceded by a comma and capitalized. │
│ • Retains all slang, grammatical errors, profanities, and exact phrases │
│ because they prove criminal intent, state of mind, or specific threat.│
│ • Example: The accused stated, "If you take one more step, I will cut │
│ your throat with this bottle!" │
├─────────────────────────────────────────────────────────────────────────┤
│ INDIRECT ATTRIBUTION (PARAPHRASE / SUMMARY): │
│ • Summarizes the general meaning without quotation marks. │
│ • Used only for non-critical administrative information. │
│ • Example: The witness stated that she had lived in the apartment complex│
│ for approximately five years. │
└─────────────────────────────────────────────────────────────────────────┘
Evidentiary Note: Never sanitize or clean up profanity in a suspect's threat. If a suspect uttered a vulgar criminal threat, transcribing it verbatim is essential to establish the statutory elements of Uttering Threats under Section 264.1 of the Criminal Code.
