3.3 Synthesizing Caller Statements: Incident Categorization & CAD Entry

3.3 Synthesizing Caller Statements: Incident Categorization & CAD Entry

[!TIP] Telegraphic Clarity in CAD Entries: CAD narratives are not narrative essays. They employ a telegraphic, objective, and chronological style that strips conversational filler, personal pronouns, and unnecessary punctuation while preserving every operational fact, descriptor, and safety warning. Every word entered into a CAD record should deliver actionable utility to field units.

In public safety telecommunications, the raw input received from the public is almost always unstructured, emotionally charged, and chronologically scrambled. A caller in distress will jump between past grievances, present fears, and fragmented physical descriptions in a single breath. The professional dispatcher’s responsibility is to act as an information synthesizer—rapidly translating chaotic speech into standardized Computer-Aided Dispatch (CAD) call text and delivering concise, life-saving radio broadcasts to patrol officers.

The Synthesis Process: From Chaotic Speech to CAD Architecture

A Computer-Aided Dispatch (CAD) system is the central database and communication suite used by 911 centers to track field units, log incident records, and dispatch calls for service. When a telecommunicator inputs data into CAD, that text is displayed on mobile data terminals (MDTs) inside patrol cruisers, fire apparatus, and ambulances in real time.

Structured CAD Call Record & Tactical Radio Broadcast (MDT / Patrol Channel)

The Three-Stage Synthesis Filter

1. Filtering Out Narrative Fluff: Discard conversational pleasantries ("Hi, I don't know who to call, but..."), subjective character judgments ("He looks like a shady criminal"), and irrelevant historical backstories ("We’ve been arguing since Thanksgiving three years ago").
2. Distinguishing Direct Observation from Hearsay: Ensure responding units understand whether a weapon was seen directly by the caller or heard second-hand from an excited child.
3. Formatting into Standardized CAD Syntax: Record facts using concise, uppercase telegraphic entries that maximize readability on mobile screens.

Direct Observation vs. Hearsay, Assumptions, and Emotional Hyperbole

One of the most frequent test traps on the POST battery involves evaluating the evidentiary credibility of caller statements. Dispatchers must strictly differentiate what the caller personally witnessed with their own senses from what they assume, heard from others, or exaggerated out of terror.

The Four Levels of Caller Input

  Level 1: DIRECT SENSORY OBSERVATION (Highest Credibility)
           "I am looking at him right now; he is holding a silver handgun."
  Level 2: SECOND-HAND HEARSAY (Requires Explicit Attribution in CAD)
           "My neighbor ran over and told me a man down the hall has a knife."
  Level 3: SPECULATIVE INFERENCE / ASSUMPTION (Do NOT Document as Fact)
           "He has his hands deep in his pockets—he definitely has a weapon!"
  Level 4: EMOTIONAL HYPERBOLE (Filter Down to Concrete Reality)
           "The whole neighborhood is completely demolished! Everyone is dead!"

Documenting Hearsay and Speculation in CAD

Failing to label hearsay can cause catastrophic tactical misjudgments. If a dispatcher types SUSPECT HAS A 12-GAUGE SHOTGUN when the caller only said "My brother told me he thinks the suspect might own a shotgun", responding officers may approach with lethal force drawn, escalating a non-violent encounter. Professional standards require clear source attribution in the CAD log:

Incident Categorization: Legal Classifications and Response Triage

Selecting the correct CAD incident type code determines whether an incident is dispatched as a priority emergency (requiring lights and sirens) or a routine patrol response. The POST battery assesses your ability to apply precise legal definitions to emergency scenarios.

+-----------------------------------------------------------------------------------+
|                         Core Incident Categorizations                             |
+-----------------------------------------------------------------------------------+
|  DISTURBANCE (PC 415)  | Verbal arguments, shouting, loud music, no physical contact|
|  BATTERY (PC 242)      | Unlawful physical force applied to another (fist, shoving)|
|  ADW (PC 245)          | Assault with a deadly weapon or force producing GBI      |
|  ROBBERY (PC 211)      | Taking property from a PERSON by FORCE or FEAR (mugging) |
|  BURGLARY (PC 459)     | Unlawful entry into a STRUCTURE/VEHICLE with intent to steal|
+-----------------------------------------------------------------------------------+

1. Disturbance / Peace Disturbance (e.g., California Penal Code 415)

Encompasses verbal arguments, noise complaints, public quarreling, and non-violent disputes. Crucially, there is no physical contact and no deadly weapon. If a married couple is screaming profanities at each other in their driveway, it is a verbal disturbance. The moment one party shoves the other, it ceases to be a disturbance and escalates to battery.

2. Battery (e.g., California Penal Code 242)

Defined as any willful and unlawful use of force or violence upon the person of another. Examples include punching, slapping, kicking, pushing, or spitting. If two patrons in a bar exchange punches but use no weapons and sustain minor scratches, the call is categorized as a physical battery.

3. Assault with a Deadly Weapon (ADW, e.g., California Penal Code 245)

An unlawful attack upon another person using a deadly weapon (firearm, knife, club, baseball bat, motor vehicle) or by means of force likely to produce great bodily injury (GBI). If a subject swings a baseball bat at someone's head, brandishes a firearm threateningly, or attempts to run down a pedestrian with a car, the incident must be classified as an ADW.

4. Robbery (PC 211) vs. Burglary (PC 459): The Critical Distinction

This is the single most commonly tested legal distinction on dispatcher selection examinations:

• Robbery (PC 211): The felonious taking of personal property in the possession of another, from their person or immediate presence, against their will, by means of force or fear. A robbery requires a human victim who is threatened, held up, or physically assaulted during the theft (e.g., a bank holdup, mugging on a sidewalk, convenience store stickup).
• Burglary (PC 459): Entering an inhabited dwelling, commercial building, or locked vehicle with the intent to commit theft or any felony. A burglary focuses on the unlawful entry of a structure. If a homeowner arrives home to find their back door kicked in and electronics missing while they were at work, it is a burglary—not a robbery—because no person was confronted with force or fear.

Formulating Concise Radio Broadcast Summaries

Once a call is entered into CAD, the telecommunicator must voice the essential facts over the radio channel to field units. A radio broadcast must take less than 15 seconds and follow a predictable, sequential cadence.

The Standardized Radio Broadcast Hierarchy

1. Alert Tone & Station Identification: High-low alert tone for in-progress violence or weapons.
2. Incident Classification & Location: Nature of crime and physical address ("Units on Channel 1, we have a 211 Robbery In Progress at 714 West Washington Boulevard...").
3. Time Lapse: How long ago the incident occurred ("...occurred one minute ago...").
4. Suspect Description & Weapons: Head-to-toe descriptors and weapon capability ("...suspect is a Male, Black Adult, early 20s, wearing a gray hoodie and blue jeans, armed with a black semi-automatic handgun...").
5. Flight Vector: Mode and direction of flight ("...last seen fleeing eastbound on Washington on foot.").

Contrasting Dispatch Summaries

• Defective / Unsynthesized Broadcast: "Attention units, a woman called crying saying her store got ruined by a crazy guy who took her money and she thinks he had a gun or knife, he was wearing dark clothes and ran outside towards the highway..." (Unstructured, lacks address, lacks specific physical descriptors, ambiguous weapon).
• Exemplary Professional Broadcast: "Unit 2A12, 2A14, 211 Just Occurred at 1204 South Broadway, Shell Station. Suspect is a White Male Adult, 30s, 6-foot, heavy build, black jacket, blue jeans. Displayed a silver revolver, took cash, last seen fleeing northbound Broadway on foot two minutes ago." (Actionable, clear, prioritized).

CAD Narrative Standards and Worked Synthesis Examples

CAD narratives are legal public records that are routinely subpoenaed in court, scrutinized by grand juries, and examined by internal affairs. Telecommunicators must uphold rigorous documentation standards:

• Maintain Absolute Neutrality: Never write subjective opinions such as "Caller sounds dishonest" or "Subject is probably high". State only observable facts: CALLER SPEECH SLURRED, INCOHERENT.
• Use Chronological Timestamping: When new information arrives, append it beneath previous lines with an update tag (UPDATE: SUSP VEH SEEN BY UNIT 4).
• Direct Quotes for Threats: When a suspect utters a specific terroristic threat or hate-crime slur, record the statement verbatim within quotation marks: RP STATES SUSPECT YELLED: "I AM GOING TO BURN THIS HOUSE DOWN".

Worked Scenario: Shoplifting Escalating to Robbery

Raw 911 Call Dialogue:

"Hi, I'm the loss prevention officer at the Target on Harbor Boulevard. We had a guy trying to steal three Dyson vacuums. When our security guard approached him at the exit doors, the guy shoved the guard to the ground, pulled a 6-inch hunting knife from his waistband, and yelled 'Back off or I'll gut you!' He ran out into the parking lot with one of the vacuums. He's a white guy, probably 35, wearing a high-vis yellow construction vest over a gray sweatshirt, green cargo pants, and a baseball hat with an American flag. He hopped into a white Ford Econoline van with ladder racks on top, and he just drove out onto Harbor heading south toward the freeway. Our guard has a scraped elbow but refuses medical attention."

Synthesized CAD Entry:

INCIDENT TYPE: 211 ROBBERY (ESTES ROBBERY - FORCE/WEAPON USED IN THEFT)
LOCATION:      Target - 2201 N Harbor Blvd, Santa Ana
RP:            Loss Prevention Officer (On Scene)

CAD NARRATIVE REMARKS:
- 14:02:11 | RP REPORTS SHOPLIFTER CONFRONTED AT EXIT BY SECURITY
- 14:02:35 | SUSPECT SHOVED GUARD TO GROUND; BRANDISHED 6-INCH HUNTING KNIFE
- 14:02:49 | SUSPECT VERBALLY THREATENED GUARD: "BACK OFF OR I'LL GUT YOU"
- 14:03:12 | SUSPECT TOOK ONE VACUUM; FLED INTO PARKING LOT ON FOOT
- 14:03:40 | SUSP DESC: WMA, ~35 YRS, HIGH-VIS YELLOW CONSTRUCTION VEST,
             GRY SWEATSHIRT, GRN CARGO PANTS, USA FLAG BASEBALL CAP
- 14:04:05 | SUSP VEH: WHI FORD ECONOLINE VAN W/ ROOF LADDER RACKS
- 14:04:22 | DOT: SB HARBOR BLVD TOWARD FREEWAY (JO ~2 MINS AGO)
- 14:04:45 | GUARD SUSTAINED MINOR ELBOW INJURY; REFUSES MEDICAL RESPONSE

This synthesis encapsulates all critical tactical variables, categorizes the incident accurately as a robbery due to the escalation of force and lethal weapon brandishing during theft, isolates the suspect and vehicle descriptors for intercept, and documents victim injuries objectively.
