Drop the Pen! What Every Writer Should Know About Real Police Work: Traffic Stops, Part Two
By David Lane Williams
Last month, we discussed traffic stops, focusing primarily on how police officers stopping vehicles based on relatively minor offenses can lead to the detection and arrest of violent criminals. Even if you’re writing a detective procedural, it’s important that you understand the constitutional and tactical considerations of a legal and safe stop in the grand scheme of policing. This month, I want to continue with the traffic stop concept, expanding on best practices. Traffic stops are performed thousands of times each day, and writers of crime fiction and true crime need to have a solid understanding of how they are performed to show they’ve done the research and know this subject better than the average Joe Citizen. There is a procedure taught at most academies nowadays, and I think it is enlightening to understand the way these things should be done. Let’s take it step by step.
Determine Reasonable Suspicion or Probable Cause
Let’s say your fictional officer needs to stop a car because the driver matches the description of a bank robber from the previous shift. Your officer needs to make the stop in a legal and safe manner. The first thing he must decide (and be ready to defend) is the legal reason for the stop. Officers in the U.S. can’t just go around stopping every car they pass. We’ve all seen the awful ramifications of such an approach. There are basically two ways to make a legal, constitutionally sound traffic stop: Reasonable Suspicion or Probable Cause.
Reasonable suspicion that a driver or occupant of a moving vehicle has committed a crime or is about to commit one is an acceptable reason for stopping a vehicle. It is, however, the least resilient tactic to the scrutiny of a defense attorney, judge, and/or jury. The officer must be able to swear under oath that, based on his training and experience, he suspected the occupants of a vehicle of doing or about to do a crime. Reasonable suspicion stops are done with less frequency than even a decade ago, because of the inevitable attack it will receive from the person’s attorney if the case ever goes to trial. Most officers will wait until they notice an infraction, such as making a turn without a signal or weaving in and out of lanes. Delaying a stop for actual probable cause—AKA evidence— instead of relying solely on suspicion, puts the officer in a better position to defend his actions if the case goes to trial.
Thus, you may opt to have your fictional officer stop a car based on a “gut feeling,” but you’ve placed him in a legally precarious situation that most veteran officers wouldn’t actually choose. It can still work, but your character is in a better position if he is patient and waits to spot an actual infraction about which he can testify under oath. (Go back and read the previous month’s article if you need more detail on the difference between a Reasonable Suspicion stop and one based on Probable Cause.)
Prepare for the Stop
Preparing for the stop means calling the license plate, description, and location to the Dispatch Center so other officers will know where you are and what kind of vehicle they should look for if the officer making the stop gets attacked. The Hollywood version of a cop stopping a car in a dark alley and not letting anyone know is macho hooey and should never happen in real life (or your fiction unless you want to show a police character performing at a level of incompetence or recklessness).
Parking the Patrol Vehicle
Safe parking of the patrol vehicle calls for turning on the emergency lights and pulling in behind the stopped vehicle. At night, a patrol officer will also use a car-mounted beacon-style light in such a way that it reflects in the side mirror of the stopped car. This adds an additional layer of protection because the other driver has limited visibility due to the glare. Officers know the glare is irritating, but it is designed to give them an edge if the occupants are intent on doing them harm.
The officer will then park the squad car at a slight angle with the engine block canted to the left. This has two advantages. First, the officer can cover behind the engine block if the occupants of the other vehicle come out shooting. Second, the parked squad car will careen to the left instead of straight into the officer if another car hits it from behind.
Approaching the Vehicle
Approaching the vehicle can be done by either stepping up to the driver’s door or around the back of the stopped vehicle just behind the passenger door. I preferred the second method when I worked at night. Most people will be watching for the officer to approach from their left. Coming up on the right side of their car allowed me to be beside the vehicle and use my flashlight to see if the occupants were holding a weapon before they even knew I was close.
Either way, officers will touch the trunk compartment door as they pass the rear fender. This action marks the suspect vehicle with the officer’s fingerprints and DNA. Should the suspect “rabbit” (flee), his car will carry definitive evidence of the encounter. It also lets the officer make sure the trunk is fully closed in case there is anyone in the trunk intent on doing him harm.
Once the officer is near the car, he should identify himself and his agency right away. This has a proven effect of calming concerns from the driver that the officer might be corrupt. Corrupt cops don’t tend to give their names, and this small detail can make all the difference in terms of keeping the tone polite and professional.
I am also a big believer that officers should clearly state why they pulled the car over, e.g., “I pulled you over because you were speeding through a school zone.” Again, this has a dampening effect on any driver revving up to argue. The officer should be clear, forthright, and professional, which is what it will sound like to jurors listening to the officer’s body camera recording if this thing ever goes to trial.
Positioning At the Vehicle
I roll my eyes at cop shows where the police officer is talking straight down into the window of the suspect vehicle. The problem with standing right beside the driver’s window is that this position puts you in the line of fire should he turn homicidal. Bullets go through car doors like toothpicks through those little Christmas party sausages. Don’t let your fictional officer stand right by the door. I’ll surmise he was poorly trained or that he is about to get shot in the groin.
Instead, officers are taught to stand adjacent to the thick metal door frame behind the driver’s seat. This space has the tactical advantage of keeping the driver in sight while also making it more difficult for him to accurately fire a weapon backward and over his left shoulder. Try it next time you’re in the driver’s seat. Point your finger like you’re a kid playing with a pretend space phaser and see if you can “photon blast” someone standing back there. You can, but it’s slow and clumsy—the advantage in a split-second attack goes to the officer.
Remember: Officer survival is part tactics and part practice, but all mindset. A well-trained police officer will be thinking about these concepts as he approaches the car.
Background Check
By now, your officer has collected pertinent paperwork, including the vehicle registration (not all states require this), proof of insurance, and the driver’s license. The officer has conversed with the occupants, determined what, if any, violations have occurred, and retreated toward his own car to increase the safety distance. Now the officer will either type in the occupants’ identification into a mobile computer or call it out to the Dispatch Center.
I preferred to keep my eyes on the car by calling Dispatch on the radio. Oftentimes, I would do this while standing behind the trunk of my own car, again so that I would have the protection of my vehicle should occupants in the stopped car come out firing. The last place I would want to be in that event would be sitting comfy—and trapped—in my driver’s seat.
Once the cop has determined there are no outstanding arrest warrants for the people in the car, he’ll decide whether to issue a warning or a citation. Once this is done, the officer needs to make a formal announcement along the lines of, “You’re free to go.”
This is where things might get tricky. Once the person who was detained has been informed he is free to go, he is…free to go. But, this is also when the officer may ask if there is anything illegal in the car. If the driver says, “No,” but he does it in a less-than-credible manner, the officer might follow up with, “So, you wouldn’t mind if I did a quick search, then?”
Why then? Why not ask to search before the officer has lifted the detention? Here’s the thing: any search of a vehicle (or anywhere considered private from the prying eyes of government) done while a person is in custody is likely to get thrown out of court. In simplest terms, a person in custody may not feel they have a choice but to let that government agent search their car. Thus, any search during the stop could, and probably should, be considered involuntary. You can’t volunteer to allow a search if you don’t believe you have an option. The case is likely to be dismissed, even if you were to find a severed head and a bloody axe in the trunk.
Officers who are looking to make lots of drug-related arrests use this tactic often. Mentioning to the driver that he is free to leave, but following up with a request to search the car is a workaround, and defense attorneys everywhere just groaned. I can’t say I blame them. This strategy pushes the limits of the Fourth Amendment, and I’m not an advocate for using it during most traffic stops. That said, this is a standard drug interdiction technique, and you may decide to use it to propel your storyline forward.
Bloody axe, anyone?
A Word on “Do you know who I am?”
I don’t care if you’re a minister taking her family out for a picnic after church, Senator So & So’s aide, or a rookie attorney who just passed the bar; cops don’t know “who you are,” and they don’t particularly care. They know they’ve stopped you for a reason, and they expect to speak with you and investigate further.
You wanna make a cop mock you long after the traffic stop? Say, “Do you know who I am?” when he approaches the car. You’ll be the belle of the squad room when he tells his buddies about it later.
That’s it for this month. Until then, be safe…just not too safe. You’ve got a job to do, after all. Onward.
