Police Jargons: A Guide to Understanding Law Enforcement Terminology
As we delve into the world of law enforcement, it’s essential to familiarize ourselves with the terminology used by police officers and other officials. From 10-13 (a radio code for “all units”) to BOLO (be on the lookout), police jargons can seem like a foreign language at first. However, understanding these terms is crucial in navigating interactions with law enforcement.
Radio Codes
Police departments use a variety of radio codes to convey information quickly and efficiently. Some common radio codes include:
| Code | Meaning |
|---|---|
| 10-1 | Unable to copy due to bad reception |
| 10-4 | Message received or understood |
| 10-13 | All units, this is [unit number] (an officer calls for backup) |
| 10-20 | Location of caller |
Common Police Jargons
Here are some frequently used police jargons:
- APB: All Points Bulletin (a notice to all law enforcement agencies to be on the lookout for a specific person or vehicle)
- BOLO: Be On The Look Out (similar to an APB, but often used by individual officers)
- CANINE: Police dog unit
- CHP: California Highway Patrol (or equivalent highway patrol in other states)
- CO: Confidential informant
- DNA: Deoxyribonucleic acid (used for forensic evidence)
Traffic Stop Terminology
When a police officer pulls over a driver, they may use specific terminology to communicate with their dispatch or colleagues:
- PULLOVER: A traffic stop is initiated when an officer requests the driver to pull over
- STOPPED VEHICLE: The officer arrives at the scene and begins to interact with the driver
- VEHICLE STOPPED: The driver has pulled over, and the officer is approaching the vehicle
Crime Scene Terminology
At a crime scene, police officers use specific terminology to document evidence and communicate with colleagues:
- BLOODSTAIN PATTERN ANALYSIS: A method used to analyze bloodstains at a crime scene
- EVIDENCE MARKING: The process of labeling and documenting physical evidence
- FINGERPRINT DEVELOPMENT: Techniques used to enhance or reveal fingerprints
Specialized Units
Law enforcement agencies have specialized units that use unique terminology:
- SWAT (Special Weapons And Tactics): A team trained for high-risk operations, such as hostage situations
- K9: Police dog unit
- AIR SUPPORT: Aerial units, such as helicopters or drones
Understanding police jargons is essential in building trust between law enforcement and the public. By familiarizing ourselves with these terms, we can better communicate with officers and stay informed about their actions.
