6.3 Pedestrian Contacts, Field Interviews & Approach Tactics

Key Takeaways

  • POST Unit V.C, Pedestrian Contacts, is a 4-hour required block that teaches the tactical execution of the legal tiers taught in Basic Law.
  • A consensual contact requires no suspicion but ends the moment a reasonable person would not feel free to leave; the officer's words, tone, positioning and number of officers all convert a contact into a seizure.
  • Colorado's stop-and-identify authority is C.R.S. 16-3-103, the codification of Stone v. People, and it permits an officer to require name, address and an explanation of the person's actions during a lawful investigatory stop.
  • The reactionary gap for a pedestrian contact is a minimum of about six feet, and the interview stance places the officer's weapon side away from the subject at roughly a 45-degree bladed angle.
  • Field interview documentation must record specific articulable facts, not conclusions; 'high crime area' alone has never been sufficient under Illinois v. Wardlow.

Pedestrian Contacts, Field Interviews & Approach Tactics

Unit V.C — Pedestrian Contacts (4 required hours) is the tactical companion to the search-and-seizure law taught in Unit II. Basic Law tells the recruit when they may detain; Patrol Procedures tells them how to stand, where to put their hands, what to say, and how to write it down. The certification examination tests both halves, frequently in the same question.


1. The Three Tiers, Applied to a Person on Foot

TierLegal predicateWhat the officer may doWhat ends it
Consensual contactNoneApproach, ask questions, request ID, request consent to searchThe person may walk away at any time
Investigatory stop (Stone stop)Reasonable suspicion of criminal activityDetain briefly, require name, address and explanation of actions under C.R.S. 16-3-103; frisk if reasonable suspicion the person is armedSuspicion dispelled, or purpose completed
ArrestProbable causeFull custody, search incident to arrest, transportBooking / release

Colorado's statutory stop authority. C.R.S. 16-3-103 codifies Stone v. People, 174 Colo. 504 (1971), and authorizes an officer to stop a person in a public place when the officer has reasonable suspicion that the person has committed, is committing, or is about to commit a crime, and to require the person to give their name and address and an explanation of their actions. The statute expressly limits the detention to a reasonable time and place. Colorado's stop-and-frisk authority under the same statute permits a pat-down for weapons when the officer reasonably suspects the person is armed and dangerous.

The conversion problem. A consensual contact becomes a seizure the moment a reasonable person would not feel free to disregard the officer and go about their business. The conversion triggers are predictable and testable: blocking the path, retaining identification or a phone, commanding rather than asking ("come here" versus "do you have a minute?"), displaying a weapon, activating overhead lights on a pedestrian, and surrounding the person with multiple officers. An officer who holds a driver's license while asking questions has seized the person, because no reasonable person walks away without their ID.


2. Approach and Positioning

         SUBJECT
            ▲
            |   ~6 ft minimum reactionary gap
     45°  ╱ |
        ╱   |
   OFFICER  |   - weapon side rotated AWAY from subject
            |   - support-side foot forward, bladed stance
            |   - hands free, above the waist, in front
            |   - back not to open doors, alleys, or traffic
     COVER OFFICER positioned at an angle that avoids crossfire

Non-negotiables from the POST curriculum:

  1. Reactionary gap. Approximately six feet minimum, extended for weapons, unknown hands, agitation, or elevation disadvantage. The gap buys the fraction of a second the officer needs to react to an action that is already faster than the reaction.
  2. Hands. "Where are your hands?" is the first tactical question of every contact. Hands kill; waistbands, pockets and closed fists are the indicators.
  3. Angle. A bladed stance keeps the duty weapon at maximum distance and protects the retention side.
  4. Background and cover. Never contact with your back to unsearched space, an open doorway, or a live traffic lane.
  5. Contact and cover. One officer talks; the other watches hands, monitors the environment, and does not join the conversation.
  6. Lighting. Light the subject's hands, not the subject's eyes, and preserve your own night vision.

3. Frisk Authority and Limits

A frisk is a separate legal event from the stop, and it needs its own justification: reasonable suspicion that this person, at this moment, is armed and dangerous. Indicators an officer should document include a visible bulge, an unnatural gait or blading, a reported weapon, the nature of the suspected crime (armed robbery versus shoplifting), furtive movement toward the waistband, and the officer's training and experience with a specific area or group.

The scope is limited to the outer clothing for weapons. Under the plain feel doctrine of Minnesota v. Dickerson, 508 U.S. 366 (1993), an officer may seize contraband whose incriminating character is immediately apparent by touch during a lawful frisk — but manipulating, squeezing, or rolling an object to determine its nature exceeds the frisk and taints the seizure.


4. Communication That Keeps the Contact Lawful

PurposePhrasing that preserves a consensual contactPhrasing that creates a seizure
Opening"Do you have a minute to talk with me?""Come over here."
Identification"Would you be willing to tell me your name?""Give me your ID." (while retaining it)
Search"May I search your backpack?""I'm going to check your bag."
Ending"You're free to go; thanks for talking with me."Silence while standing in the person's path

When the encounter is a lawful Stone stop, the officer should say so plainly — "You're being detained while I investigate a report of a burglary in this block" — because that statement simultaneously satisfies the tactical need for compliance and creates the record that supports the detention.


5. Writing the Field Interview

A field interview report or FI card is worthless if it records conclusions. The suppression hearing is decided on specific articulable facts.

Weak (conclusory)Strong (articulable)
"Subject was acting suspicious.""Subject stood at the rear of a closed business at 0230, looked over both shoulders three times, and pulled his jacket closed over his waistband when he saw the patrol car."
"High crime area.""Three burglaries reported in this two-block area in the past 14 days, and this business was burglarized on 8/9."
"Subject appeared nervous.""Subject's hands shook, his carotid pulse was visibly rapid, and he answered questions about his address inconsistently three times."

Illinois v. Wardlow, 528 U.S. 119 (2000), holds that presence in a high-crime area combined with unprovoked headlong flight may support reasonable suspicion — but the case also makes clear that the location alone never does. Colorado suppression practice follows the same rule, and the report is where the officer wins or loses it.

Finally, document the ending. Note the time the contact concluded, whether the person was released or detained further, and whether they were told they were free to leave. Body-worn camera under C.R.S. 24-31-902 will show all of it; the report should match.
