In police terms, a BOLO stands for "be on the lookout." It's an official alert or broadcast sent to law enforcement officers—and sometimes shared with the public—to gather information, locate a missing person, find a fleeing suspect, or recover stolen property. When a dispatcher broadcasts a BOLO over the radio or transmits it through a digital database, every receiving unit knows to scan their immediate patrol area for specific identifiers.
Understanding how police agencies construct, distribute, and manage these alerts reveals a core mechanism of modern police communication. This guide breaks down what a BOLO means, how officers use them during shifts, what information they contain, and how they differ from other law enforcement bulletins.
What is a BOLO?
A BOLO is a standardized notice used across local, state, and federal agencies to share urgent intelligence about a subject of interest. While television shows often romanticize them as high-speed highway chases, a BOLO can cover a wide range of administrative and investigative situations.
The core purpose is rapid dissemination. If a convenience store robbery occurs on the east side of town, the responding officers gather a description of the suspect and the getaway car. Within minutes, dispatch compiles those details into a BOLO and transmits it to all units working the current shift, as well as neighboring jurisdictions.
Unlike a formal arrest warrant, which requires a judge's signature and establishes probable cause for an arrest, a BOLO is often built on reasonable suspicion or preliminary witness statements. It serves as an investigative tool to help officers spot patterns, make contact, and develop the probable cause needed for further legal action.
Core Elements Contained in a BOLO
An effective BOLO doesn't just throw out vague descriptions; it relies on specific, actionable data points. Law enforcement training emphasizes precision so that patrol officers can make split-second decisions safely.
- Subject Description: This includes physical traits such as height, weight, race, hair color, eye color, facial hair, tattoos, scars, or distinct clothing.
- Vehicle Identifiers: If a vehicle is involved, officers look for the "CYMBALS" rule: Color, Year, Make/Model, Body style, And, License plate, State. Unique damage, custom rims, or bumper stickers are also highlighted.
- Last Known Direction: Officers need to know the trajectory. Did the subject run on foot eastbound toward a subway station, or drive northbound on the interstate?
- Threat Level and Caution Notes: If the subject is considered armed, violent, or an escape risk, the BOLO will explicitly state it. This warning dictates whether responding officers wait for backup or approach with heightened caution.
- Associated Persons or Locations: Names of suspected associates, known hangouts, or home addresses give investigators secondary places to check.
Operational Use in Daily Policing
Police officers encounter BOLOs at the start of every shift during roll call, where supervisors brief teams on active regional alerts. Digital mobile data terminals (MDTs) mounted inside patrol cruisers also display active local BOLOs continuously.
Traffic Stops and Patrol Scans
During routine patrol, officers mentally cross-reference vehicles and pedestrians against active BOLOs. If an officer spots a vehicle matching a broadcasted license plate or description, they initiate a traffic stop to investigate further. Because a BOLO often lacks a signed warrant, the stop must adhere to constitutional standards—usually requiring reasonable articulable suspicion that the occupant was involved in a crime.
Inter-Agency Coordination
Crime doesn't stop at city limits. Regional information-sharing networks allow police departments to push BOLOs across county and state lines instantly. If a suspect commits a felony in a rural county and flees toward a major metropolitan area, neighboring agencies receive the BOLO before the suspect even crosses the boundary line.
Publicly Distributed BOLOs
Sometimes agencies release BOLOs to the public through press releases, social media, or dedicated programs like the BOLO Program. Public participation drastically increases the eyes and ears on the ground, especially when hunting for missing endangered persons or high-risk fugitives.
BOLO vs. Other Police Bulletins
Law enforcement terminology includes several types of notices. Confusing a BOLO with other administrative notices can lead to miscommunication.
- BOLO vs. Amber/Silver Alert: An Amber Alert (for abducted children) or Silver Alert (for missing vulnerable adults) is a specialized, highly regulated public emergency broadcast system. While an Amber Alert functions similarly by telling people to watch for a vehicle or child, it triggers emergency wireless emergency alerts on cell phones, whereas a standard BOLO remains internal or localized.
- BOLO vs. ATL (Attempt to Locate): In many departments, "ATL" and "BOLO" are used interchangeably. However, some agencies use ATL specifically for missing persons or welfare checks, while reserving BOLO for criminal suspects and vehicles of interest.
- BOLO vs. Wanted Poster / Warrant: A warrant is a legal command backed by a judge. A BOLO is an operational communication tool that may or may not be tied to an active warrant at that exact moment.
Common Misconceptions About BOLOs
Pop culture often distorts how law enforcement agencies utilize these alerts. Clarifying these myths helps set realistic expectations about police work.
- Myth: A BOLO gives officers automatic authority to search anyone. Officers still need legal justification—such as consent, plain view, or probable cause—to search a person or vehicle stopped via a BOLO.
- Myth: BOLOs stay active indefinitely. Most police departments automatically purge or deactivate standard operational BOLOs after a set period, such as 7 to 14 days, unless an investigator manually extends it for serious felonies like homicide.
- Myth: Only police officers issue them. While law enforcement issues official operational BOLOs, private security operations also use pass-down notes and internal BOLOs to monitor trespassers or banned individuals on private property.
Frequently Asked Questions
What happens when the subject of a BOLO is found?
Once the person, vehicle, or property is located, the handling officer notifies dispatch. The originating investigator verifies the contact, conducts the field interview or arrest, and updates the database to deactivate the BOLO so other units stop searching.
Can citizens report information that triggers a BOLO?
Yes. When a witness calls emergency services to report a reckless driver or a suspicious person peering into windows, dispatchers evaluate the credibility of the report and may generate a localized BOLO for nearby patrol units.
Are BOLOs restricted to vehicles and suspects?
No. Law enforcement agencies frequently issue BOLOs for stolen property, ranging from high-end construction equipment and firearms to stolen artwork or license plates entered into national crime databases.
Do BOLOs cross international borders?
Major federal agencies like the Federal Bureau of Investigation coordinate with international bodies like INTERPOL to share multi-jurisdictional alerts, which serve a similar function to domestic BOLOs on a global scale.
