Study Notes

Legal Justification for Stopping a Vehicle

Two legal justifications required to stop a vehicle:
- Probable cause of a traffic offense
- Reasonable suspicion that the vehicle or its occupants are in violation of some law

Selecting the Best Location for a Traffic Stop

Avoid stopping at:
- Drinking establishments
- Housing projects
- Public parks
- Fast food hangouts
- Curves
- Hills
Consider cover options:
- Trees
- Hydrants
- Large rocks

Information to Provide to the Dispatcher

License number
Description of vehicle
Exact location
Number of visible occupants
Apparent description of occupants
Call for backup on all high-risk or felony stops and when assistance is needed

Positioning the Police Car

Unknown risk stop:
- Position patrol car approximately 15 feet to the rear and 3 feet offset to the driver's side of the suspect vehicle
- Fully illuminate the other vehicle interior and occupants
- Read the license plate without having to re-deploy the patrol car
High-risk stop:
- Position the police vehicle approximately 30-40 feet behind the suspect vehicle

Approaching the Vehicle

Park patrol car approximately 15 feet to the rear and 3 feet offset to the left of the violator's vehicle
Throw a blinding flood or light inside the violator's vehicle at night
Before exiting, ensure the ignition of the violator's vehicle is turned off
Before moving past the limited cover of the open car door, gain a "visual on" and control of the violator's hands
Reach a position that looks non-threatening to the ordinary citizen, but appears unchallengeable to would-be assailants

Actions of the Assisting Officer

Unknown risk stop:
- Stand behind the passenger door of the patrol car with access to the radio and shotgun
- Have a means of communicating with the approaching officer
- Move to the right rear of the violator's vehicle once the approaching officer has established there's no detectable threat
High-risk stop:
- Stand behind the passenger door or nearby cover, keeping a shotgun trained on the suspect vehicle
- Serve as a control-and-arrest officer

Removing Vehicle Occupants

Unknown risk stop:
- Removing occupants is not recommended, but be prepared to escalate to high-risk stop mode if necessary
High-risk stop:
- Locate the stop to your advantage
- Illuminate the suspect vehicle
- Get behind cover
- Announce your purpose and take charge
- Order the suspect vehicle immobilized
- Command the occupants to stay inside and hold hands up
- Maintain surveillance with a shotgun or rifle trained on the suspect(s)
- Stabilize the situation until enough manpower is available to proceed

High-Risk Vehicle Stops

Include:
- Felony stops (verified)
- Wanted person stops
- Suspected felony stops
Considerations for choosing a location:
- Avoid stopping on a hill or curve
- Avoid stopping in a traffic lane or in front of a trouble spot
- Try to stop in a well-lit area
Positioning patrol vehicles:
- 30-50 feet behind the felony vehicle
- Angle the car at 45 degrees for extra protection

Unknown Risk Stops

Tactics:
- Choose a location carefully
- Position your vehicle properly
- Avoid rushing your approach
- Prior to leaving the police car, notify your communications
- Reach a position that looks non-threatening to the ordinary citizen, but appears unchallengeable to would-be assailants

Threat Zones

Crisis Zone: a strip about 20 inches wide that starts at the violator's rear bumper and ends about 10 inches away from the driver's window
Reach Zones: extend forward an arm's length or so from where the Crisis Zone ends
Point Reflex Zone: fans out from the back corner of the driver's (or passenger's) window at about a 45° angle to the Crisis Zone
Target Zone: arcs from where it overlaps the Point Reflex Zone around to the front fender of the vehicle

Procedure for Removing Vehicle Occupants

Roles of Command Officer, Cover Officers, and Contact Officer
Command Officer:
- Covers the felony vehicle using his handgun
- Issues loud verbal commands to the occupant(s) of the felony vehicle
Contact Officer:
- Commands the suspect(s) after the Command Officer talks the suspect(s) back to a specified point
- Takes the suspect(s) into custody
Cover Officers:
- Maintain constant surveillance of the suspect vehicle and the surrounding area
- Provide cover for the Command and Contact Officer by using their handgun or a shotgun to establish a constant threat of risk or danger to the occupants of the suspect vehicle### Racial Profiling Law
The law is found in RSMo 590.650 and 590.653, effective December 7, 2000.
It requires peace officers to report certain information for every traffic stop.

Reporting Requirements

Age, gender, and race or minority group of the individual stopped.
Traffic violation or violations alleged to have been committed that led to the stop.
Whether a search was conducted, and if so, details about the search.
Whether any contraband was discovered, and if so, the type of contraband.
Whether any warning or citation was issued, and if so, the violation charged.
Whether an arrest was made, and if so, the crime charged.
Location of the stop.

Context and Purpose

The law was passed because of concerns about minorities being stopped by peace officers due to their minority status.
The law does not prohibit vehicle stops based on reasonable suspicion of a crime.
Reasonable suspicion requires articulable suspicion, meaning the officer must be able to put their suspicions into words.
The more reasons the officer can articulate, the greater weight or value their suspicions will have.

Review and Quiz

The instructor will review the objectives, clarify questions, and verbally quiz trainees on objective responses.
