“Perception is key. How did the officer perceive the encounter? Did she fear for her life or the life of others?”

Before we delve into the topic of perception, please allow me to set the stage by using an experience from my past. I apologize in advance for rehashing the tale, but its use here perfectly  illustrates the information below.

Many of you have heard me speak about the deadly shootout I was in back in the 90’s. Others have read the story here on this blog. In both I tell of the involuntary engagement of a “slow motion switch,” and the switching-off of all sounds.

The shooting seemed to occur in slow motion while in a vacuum where sounds were not permitted to enter.

FYI – Pictured above is the robber’s car. I fired the round that penetrated the side and rear glass of the car. At the time, the robber had already begun shooting but the only part of his body I could see was his head. That view was through both panes of glass. My round struck the side of his head. He immediately went down, but almost immediately returned to his feet and resumed shooting.

The large hole in the side of the car just above the wheel well was fired by a rookie officer who was fresh off his field training program. The  round was fired from a shotgun. The “slug” was later found in the rear compartment, inside a duffle bag filled with clothing.

Sights, Sounds, and Auditory Exclusion

FYI – Pictured above: A police car destroyed by gunfire. That’s me in the foreground, with the porn star/cop mustache and my sweaty hair pulled behind my ears. A state agent who’d responded to assist stands behind me near the shoulder of the highway. The suspect’s vehicle is pictured in the distance, directly to my rear. My partner’s unmarked vehicle is seen parked on the opposite side of the median, top right. He’d been in court when he learned of the shooting and had arrived on-scene at the conclusion of the incident.

It was an extremely hot August day and I’d worn a suit. I was preparing to go to court when the call came in, a 10-90—robbery in progress. Mere moments prior to the news reporter taking this photo, I’d killed a man.

FROM MY EARLIER ARTICLE:

“The sound of his gunshot activated my brain’s slow-motion function. Time nearly stopped. It was surreal, like I actually had time to look around before reacting to the gunshot. I saw my partners yelling, their mouths opening and closing slowly. Lazy puffs of blue-black smoke drifted upward from their gun barrels. I saw a dog barking to my right—its head lifting with each yap, and droplets of spittle dotted the air around its face.”

During the exchange of gunfire, I saw the mouths of partners moving and I saw a dog barking, but I did not hear either. The reason I didn’t—auditory exclusion.

Auditory exclusion, like it’s first cousin, tunnel vision, can and does often occur during moments of intense stress, such as life-threatening situations including shootouts or potential shootouts. Actually, guns don’t have to enter the picture for these stress-induced phenomena to occur. However, that’s the focus of this article so that’s the path we’ll travel today.

Stress can interfere with our physiological ability to receive and act on information

In very simple terms, stress can interfere with our physiological ability to receive and act on information received by the brain. Basically, we’re wired to survive and we do so by fighting or fleeing and sometimes freezing in place/not reacting during dangerous situations.

Typically, when faced with danger our bodies automatically increase the release of adrenaline and cortisol, which produces an uptick in heart rate, blood pressure, breathing rate, pupil size, perspiration, and muscle tension. Blood flow to the brain, heart, and large muscles is accordingly increased. However, fine motor skills that require hand/eye coordination begin to deteriorate. This decrease in the functionality of fine motor skills allows the continuation of the more effective (at the time) gross motor skills that help when running or fighting.

One way our bodies react to intense stress is to induce inattentional blindness, a phenomenon that reaches across all senses, including vision (tunnel vision) and sound (auditory exclusion). In short, the brain processes only what the person/officer is focused on, such as a potentially deadly threat. In my case, it was a bank robber who was firing a gun at me and I know that auditory shutdown is a very real thing during high-stress situations. Again, this is from my own personal experience.

NOTABLE POINTS REGARDING PHYSIOLOGICAL RESPONSES TO STRESS

  • Optical affinity can occur—increased ability to see things at 20 feet and beyond while closer objects may seem blurry, if seen at all. The same is true for near shutdown of periphreal vision. The latter is due to vasoconstriction of the blood vessels on the periphery of the retina (tunnel vision).
  • Perceptions are often distorted, such as the ability to correctly perceive a danger.
  • Sounds are processed by the brain faster than what we see. Touch is the next fastest, and smells reach the brain the quickest.
  • Motion is recognized faster than than color, and shape is slowest of all sights processed. Yellow is the fastest color we can identify. Darker colors being the slowest.
  • Furtive movement – done in a quiet and secret way to avoid being noticed (Webster’s).
  • During stressful encounters, such as those involving deadly force, furtive movements (see above definition) are sometimes perceived incorrectly, such as the movement of hands holding a dark object whose shape somewhat resembles a firearm. but understandably so when factoring in physiological phenomena such as auditory exclusion and tunnel vision.

I See Colors. Or Do I?

Remember, darker colors are identified at a slower rate than bright colors, acute vision at closer distances is greatly decreased, sounds have all but ceased to exist, adrenaline and heart rate are higher, officers are trained to fight not flee from danger, and officers are trained to react to threats. And all of this occurs in a the blink of an eye. There is no time to sit down, discuss, plan, and map out the premium response. This is wholeheartedly in contrast to the armchair cop experts who chime in after the fact with the uninformed, misinformed, social-media-educated, and inexperienced “cop’s are too quick to shoot”comments.

  • Our minds, during stressful situations, see what they expect to see. We expect a man suddenly pulling a dark object from his pocket after repeatedly telling him to not put his hands in his pocket, all while knowing he matches the description of a guy who’d just shot and killed four people, well, our minds are telling us he’s going for a gun.

If the object he brings from his pocket is dark, such as a cellphone, a vaping pen that looks like a gun barrel, especially when held like a gun and pointed at officers, a BB gun that’s nearly identical to the officer’s duty weapon, or even a bare hand that comes up and out of pocket rapidly, and the movement is in contrast to the officer’s direction and expectations, and it all occurs within a split second, well …

Remember, sound is perceived before sight, motion is perceived before color, and color is perceived before shape. These differences can and do greatly affect how an officer perceives and processes what’s unfolding in real time. And, those perceptions will definitely affect and/or control the officer’s response(s).

I can say from experience that during a potentially life-threatening situation, barking dogs, screaming officers, sirens, and gunshots are sometimes the loudest sounds you’ll ever NOT hear.

After an intense shootout with an armed bank robber, I shot and killed the man (68 rounds were exchanged—I fired 5). That’s him above as emergency medical personnel treat him.

Even today, at this moment seated here at my desk, I can hear the deafening quiet of that morning. And I still view parts of the scene in slow motion.

By the way, not once during the entire shootout did I or the other officers smell the odor of cordite lingering in the air. Why not? Because the stuff hasn’t been around since the end of World War II. So please, please, please stop writing it into your stories.

 

The pursuit ended when the fleeing felon crashed his car in a roadside ditch. Both he and a passenger hopped out and began running toward an open field. The passenger turned right at a stand of maple trees. The driver hooked left, aiming for the rear of an elementary school. He carried a pistol in his left hand.

The dispatcher called to the officer to report that the driver was wanted for killing two police officers in a nearby town. The pursuing officer, D.O. Nut, chased the suspect, picking up speed and gaining on the armed man. His partner ran after the passenger.

Officer D.O. Nut felt his heart pounding against the inside of his ribs, its intensity mirroring the rapid rat-tat-tatting of a Thompson Sub-Machine gun. He felt his muscles quivering and he sensed a sudden burst of energy (no way he could run this fast and this far on a typical day).

In spite of his wide open mouth that sucked air as hard as his lungs would allow, he seemed fine, as if he could keep up the pace all day long. His vision was sharper than usual and his mind processed information at lightning speeds. He was invincible.

He caught up to the the cop-killer, an extremely large, muscular man the size of a pro wrestler, and quickly took him to the ground where he aptly placed cuffs around his massive wrists and then pulled the struggling behemoth to his feet for the long walk back to the patrol car. Piece of cake.

Adrenaline is definitely bad to the bone!

The officer suddenly felt a bit dizzy due to the change in blood circulation and oxygen. The temperature was a bit cool out, yet he felt somewhat warm and was perspiring far more than normal.. It was nearly an hour later before the odd feelings subsided.

That’s how it is for a police officer, the rollercoaster ride of adrenaline rushes and crashes/dumps, over and over again throughout a typical shift. From 0-100, time and time again. Guns, knives, fists, pursuits, yelling, screaming, crying, hostages, suicides, murders … STRESS!

The Adrenal Gland

Adrenaline, a simple stress hormone, aka epinephrine, is produced within the adrenal gland, a small gland that’s perched on the tops of our two kidneys. But as tiny as it is, the gland is the powerhouse behind our incredible “fight or flight” responses to fear, panic, and/or perceived threats.

Adrenaline is produced by a very specific layer of tissue within the adrenal gland—the medulla (the middle tissue). The gland also synthesizes many other hormones but that’s for another day, possibly. For now, let’s maintain our focus on adrenaline and how it’s so very important to police officers, victims of violent crimes, and the everyday Joe or Jane.

The Adrenaline “Rush”

An “adrenaline rush” occurs when the Sympathetic Nervous System is involuntarily activated by the brain when it detects that we’re involved in a high stress event, such as imminent physical danger.

When we’re frightened by a life-threatening situation such as an armed robber or serial-killer-maniac, the brain senses the danger and immediately sends an instant message to the adrenal glands. When the adrenal gland receives the alarm, and it’s an instantaneous reaction, it leaps into action and quickly dumps a massive surge of adrenaline into the bloodstream.

Once adrenaline is released and snakes its way throughout the body, it begins to work its magic—releasing glucose into the bloodstream to generate extra energy, speeds up our heart rates and increases the thumping power of the heart’s contractions, and it dilates the blood vessels.

To increase our intake and exchange of oxygen, adrenaline also widens the bronchioles, the smaller airways in the respiratory tract that lead to the alveolar ducts and finally to the extra-tiny alveoli (in the lungs) where gases are exchanged with blood.

Alveoli, by the way, are tiny air sacs located in the lungs at the end of the bronchioles. The alveoli are where the lungs and the bloodstream exchange carbon dioxide and oxygen.

Speaking of Alveoli

I apologize for rambling but, since we’ve brought up the alveoli I’d like to take a brief moment to mention their part in breathalyzer testing. I know, it has absolutely nothing to do with the topic of the day but it’s cool information that could someday be needed in a work of fiction, so here you go.

As blood is pumped throughout the body it passes through the lungs where it is is oxygenated. As a result, when a person consumes alcoholic beverages some of the alcohol eventually crosses the air sacs (alveoli). When it reaches those sacs alcohol is released into the air. This occurs because because alcohol evaporates from a solution because oxygen is volatile.

Therefore the concentration of the alcohol in the alveolar air corresponds to the concentration of the alcohol in the blood. When the alcohol in the alveolar air is exhaled (deep lung air), it can be detected and accurately measured by breathalyzers and other breath alcohol testing devices such as those used by police officers.

The ratio of breath alcohol to blood alcohol is 2,100:1, meaning that 2,100 milliliters (ml) of alveolar air contains the same amount of alcohol as 1 ml of blood.

Whew! That Was Confusing, Right? And I had to endure a week of classroom training about this stuff back during Breathalyzer certification training. Fun times!

Okay, Now Back to Adrenaline

We’ve all experienced an adrenaline rush at some point during our lives. Like when the car nearly crashed into you on the freeway, or during your PIT maneuver training at the Writers’ Police Academy as your car was struck by one driven by Tami Hoag or Craig Johnson, a controlled collision that caused your vehicle to wildly spin out of control.

Fight or Flight

Now, with our bloodstream loaded with adrenaline, we’re ready to either stand and fight or put our feet in action to make a speedy retreat. Fortunately, we don’t have to develop this plan before we act because our autonomic nervous system does it for us. It’s this automated control center of our nervous systems the start the process for us. All we need to do react in whichever method—to run away or stand and fight—our bodies tell us.

If we’re forced to fight during the time when adrenaline is surging through our blood vessels, well, Mr. Bad Guy had better prepare for a wild ride because fear can bring out the grizzly bear in each of us. It is this physical response that can aid in fending off those who mean to do us harm.

Adrenaline is indeed a remarkable thing. Once it’s sent on its way through the bloodstream, it can turn the meek and mild into supercharged versions of themselves.

The Tractor and a Child’s Superhuman Strength

An uncle of mine lost his legs after a farming accident when a tractor he was driving slipped on a hillside and overturned, pinning him beneath it. His young son, just a small boy, witnessed the accident and miraculously lifted the tractor from his father who then managed to pull himself away. The boy then released his hold on the tractor and it fell to the ground. Unfortunately, both of my uncles legs were crushed and had to be removed.

He went on to live a productive and active life, though, and never let his handicap slow him in any way. He even enjoyed joining in a game of softball once in a while. He was a killer with  bat and could easily slam a ball into deep center field. Then he’d “run” the bases by using his hands to thrust his torso forward and back much like the movements of a chimpanzee scampering along the ground. My goodness, my uncle was fast, too. He’s gone now, but his story and love of life and family left a lasting impression on many people.

But, my uncle would have succumbed to his injuries had it not been for his son’s quick thinking and and adrenaline-charged super strength. And it is that same “rush” that helps cops survive each and every day.

But those ups and downs can take a toll on the body.

Short term, immediate post adrenaline “dumps” often result in:

  • Nausea
  • Mild to Extreme Muscle Soreness
  • Urge/Desire to have sex. Hypersexual.
  • Winding Down Process – hyper activity such as extreme pacing,  jitteriness, shouting, and incessant babbling.
  • Exhaustion
  • Nightmares and Loss of or Restless/Tossing and turning during sleep
  • Sporadic Adrenaline Rush brought on by a minor incident or thoughts

Long term effects include:

  • weakened immune system
  • ulcers
  • cardiovascular troubles
  • Stress-induced DNA damage that can lead to premature aging, promotion of tumor growth, miscarriages in women
  • depression
  • exacerbated anxiety
