Objective Writing, Field Notes, and Incident Narratives

Why Objective Writing Matters in Forensic Work

Every word a forensic technician writes becomes part of the legal record. Field notes, reports, and incident narratives can be subpoenaed, read aloud in court, and challenged by defense attorneys. A single careless phrase—"the suspect clearly panicked"—can undermine an entire case, expose the agency to liability, and damage your credibility as a witness. The standard is simple: write only what you directly observed, measured, photographed, or collected. Leave interpretation to the attorneys, detectives, and expert witnesses whose role it is to draw conclusions.

Field Notes: Your Real-Time Record

Field notes are the raw, contemporaneous record you create while working a scene. "Contemporaneous" means written at the time of observation, not reconstructed from memory hours later. Courts give contemporaneous notes significant weight precisely because they were made before memory fades or outside influences intervene.

Every entry must include:

• Date and time of each observation (use a 24-hour clock for clarity)
• Location described precisely—room name, compass direction, distance from a fixed reference point
• Item description using neutral, observable language: color, size, shape, texture, position
• Conditions such as lighting level, weather if outdoors, and temperature if relevant
• Your name and role on every page

Number your pages and never leave blank lines between entries. If you make an error, draw a single line through it, initial it, and continue. Do not erase, use correction fluid, or destroy any page. Destroyed or altered notes suggest tampering to a jury.

Objective vs. Subjective Language

Objective language describes what the senses detected. Subjective language inserts opinion, emotion, or conclusion. Compare:

| Subjective (avoid) | Objective (use) |

|---|---|

| The room was ransacked violently. | Drawers were open and contents were on the floor in the northeast bedroom. |

| The suspect clearly struggled here. | A lamp was overturned near the east wall; a broken ceramic fragment measuring approximately 6 inches was located 2 feet south of the lamp base. |

| The victim tried to escape. | Drag marks consistent with a shoe sole pattern were observed on the hallway tile, extending 4 feet from the bedroom doorway toward the front entrance. |

Notice that objective statements use passive or neutral constructions and always anchor observations to specific locations and measurements. Words like "clearly," "obviously," "violently," and "attempted" imply interpretation and must be avoided.

Legal Risk of Opinion Language

When a report contains an unsupported conclusion, a defense attorney can argue that the technician prejudged the scene before completing a neutral examination—a form of confirmation bias. This can lead to exclusion of evidence, dismissal of charges, or a successful appeal. In civil cases, opinion language in official reports can expose the agency and the individual technician to claims of bias or misconduct. Stick to facts and you protect the case, your agency, and yourself.

Incident Narrative Structure

The incident narrative is the polished written account submitted as part of the official case file. It translates your field notes into a formal, chronological story of what you did and observed. A compliant narrative has four components:

1. Header — case number, date, time of response, location, reporting technician, and supervisor

2. Arrival and scene conditions — your exact arrival time, who you received the scene from, and initial observable conditions (lighting, weather, status of doors and windows)

3. Examination account — a chronological, zone-by-zone or area-by-area account of what you observed and collected, written in past tense, first person, with precise locations and item numbers that match your evidence log

4. Conclusion of processing — time you completed work, who you released the scene to, and any notes about chain of custody handoffs

Use short, declarative sentences. Avoid pronouns that are ambiguous ("he," "she," "they" without a clear antecedent). Spell out abbreviations the first time they appear. Proofread for grammar and spelling—errors signal carelessness to jurors.

Grammar and Formatting Standards

Law-enforcement documentation norms require:

• Past tense throughout (you are reporting what already happened)
• First person for your own actions ("I photographed...", "I collected...")
• Active voice where possible for clarity
• No slang, jargon, or emotionally loaded words
• Metric or standard measurements written consistently throughout one document

Safety Note

If field note-taking requires you to enter an area where biological, chemical, or physical hazards are present, you must don appropriate PPE before entering—regardless of how quickly you want to capture an observation. No note is worth exposure to bloodborne pathogens, chemical residue, or structural collapse risk. Never handle an item to get a better look before it has been documented in place. Document first, collect second, always.

Passing the Check

Your incident narrative must score 80% or higher overall on the rubric, with no category scoring below 70% in objectivity. Peer reviewers will flag opinion language, missing location references, and chronological gaps. Use their feedback before your final submission. Strong narrative writing is a skill employers and credential examiners test because it is the technician's most durable contribution to a case.
