Stress of the Job

Download this post – Stress of the Job (3)

There’s a cost to any business. For professional law enforcement officers, military personnel, or Federal agents the cost is wear on tear their body from the years of cumulative stress. There is a relatively recent hypothesis that asserts that there is physiological risk associated with exposure to psychosocial stressors over time. In lay speak, folks in high stress jobs will suffer physical ailments because of the pressures of the job.

The term for the chronic exposure to stress and its effect on the body is referred to as the allostatic load. This term was coined by McEwan and Stellar in their 1993 text entitled “Health Psychology” published by McGraw-Hill. Allostasis could be literally defined as “maintaining stability through change.” From an NIA Exploratory Workshop on Allostatic Load in 2007:

“Allostatic load refers to the cumulative biological wear and tear that can result from excessive cycles of response (i.e. too frequent and/or of inappropriate duration or scope) in these systems as they seek to maintain allostasis in the face of environmental challenge [someone assaulting you].  According to the theory, as these systems become taxed and dysregulated, they begin to exhibit imbalances in the primary neural mediators of the stress response…”

Stressful situations can limit brain functions to basic levels, the much discussed “fight or flight” response.  Allostatic load is impacted by repeated cycles of this response.  Over time the allostatic load can cause changes in the physiological response to stressors.  The police officer who once responded within a moral and ethical framework may begin responding with inappropriately high levels of anxiety and aggression.

Obviously, the implications for the theory is that there are long-term health consequences to having a job with an unusually high allostatic load. The stress of the job can kill you. It’s worth understanding the threat and how to mitigate it for the same reasons you practice with firearms. From a 2005 UCLA study:

“The body’s perception of stress leads to a significant load upon physiological regulation including circadian regulation, sleep and psycho neuroendocrine-immune [link between psychological factors and the nervous and immune systems] interaction.”

Besides a physical toll, there is a psychological toll to this phenomenon as well.  It is well documented phenomenon that acute stressors can cause PTSD in soldiers, law enforcement, or other victims of traumatic events.  The frontal executive areas of the brain are responsible for planning, decision making, and judgement.  This area is affected by the experiences that pass through it.  The frontal areas of the brain are constantly “tuned” by experience.  When two cells fire together, they are wired together.

In a recent FBI study entitled Brain Functioning as the Ground for Spiritual Experiences and Ethical Behavior a veteran law enforcement officer commented “Peace officers are exposed to the worst that life has to offer.  They see the denizens of society at their very worst – when they have just been victimized or when they have just victimized someone else.  Peace officers see the perpetrators of evil and the results of their evil deeds.  The constant contact with evil is corrosive, and those effects are cumulative.”

The author (Dr. Fred Travis) further writes that “Experiences change the brain.  This is inevitable.  The violence law enforcement officers see becomes part of the functioning or their brains and bodies.  Neural imaging assessed activation of the areas of the brain that stop wrong behavior, called orbitofrontal cortex, after individuals…” witness or experience violent, traumatic events.

Allostatic load can reduce connections with frontal executive areas of the brain and amplify stimulus-response circuits.  These changes, or structural remodeling, can impact memory and emotions and may increase anxiety and aggression.  Victims of these changes may become distant from spouses, children, or other friends because they are emotionally incapable of interacting or feel a sense of detachment.  Neural imaging of patients who experience high allostatic load reveal lesions on the frontal executive areas.  The brain is intact, but the brain matter is no longer involved in planning and decision making.

The impact on job performance can be devastating.  Extreme errors in judgement, non-ethical or immoral decision making, and dereliction of responsibilities can all result from years of high stress and allostatic overload.

How then, do we combat allostatic load?   There are, of course, many prescription drugs available that can help mitigate the effects of allostatic load.  Somewhat surprising, at least to me, is another non-pharmaceutical option.  The solution may well be spirituality.  Spirituality, loosely defined as a sense of wholeness, has been shown to engage the entire frontal executive area of the brain.

Spirituality can obviously be religious.  The research conducted by Dr. Travis, however, is more general.  Any experiences that are universal in nature, or ones that transcend our own sense of time, space, or individual body can be spiritual.  The effects of spirituality on the brain are widespread activation and higher brainwave coherence.  The measure of this phenomenon is known as Brain Integration Scale (BIS).

People who regularly practice spirituality have a correspondingly higher BIS.  They become more self-reliant, self-sufficient, independent, and take responsibility for their lives and performance.  BIS studies have shown a positive correlation between spirituality and emotional stability and moral reasoning, while showing a negative correlation with anxiety.  BIS is increased with regular spiritual experiences.

For professional soldiers and police, the conclusions are fairly straightforward.  Each of you will react differently to the stress of your jobs.  Over time, the cumulative stress may negatively impact your physical and/or psychological health.  An otherwise good, moral officer will make immoral choices and could become extremely anxious or aggressive.

For me, there is a certain elegance to the allostatic load theory.  Becoming involved in your local church and establishing a healthy relationship with God will help you reach your potential as a husband, a father, and law enforcement professional.  This foundational relationship will help you manage allostatic load and facilitate success both at home and at work.  It provides balance to your life and will allow you to formulate the best decisions, even when under extreme stress.

Fight Stopper

Anytime you’re in a fight, particularly a gunfight, halting your adversary is the goal.  When you’re in a fight, you just want out of the fight.  You can disengage, run, or neutralize your attacker.   Or you can be killed.

Once your attacker has commenced his assault, stopping him becomes your life’s work.   The firearm most likely available to you will be your handgun.  If you are aware of the impending attack, you’ll most certainly arm yourself with a long gun.  Since most attackers won’t afford you that opportunity, proficiency with your pistol remains paramount to your survival.  Because of the array of pistol manufacturers, models, and calibers available, there is inevitably a debate about which combination is “best.”  I am frequently asked to give my opinion on caliber selection.  Even more than training, or tactics, or weapons selection.  Everyone loves talking about ballistics.  The problem is that most of us are knuckle-draggers and we only know two things about ballistics…jack and shit.

We get on the internet and google and read and talk to our buddies who seem to know a lot about guns.  I’m no different.  I’ve been amassing articles and studies about ballistics for as long as I can remember.  This is my attempt to solve the “caliber riddle.”

First off, lets talk about knock-down power.  Simply put, it doesn’t exist.  The force a bullet will impact your adversary is equal to (or less than) the recoil you felt when you fired the round.  It’s physics.  It isn’t debatable.  If you fired a bullet capable of knocking someone to the ground, you would likewise be knocked to the ground when you triggered it.  Every action has an equal and opposite reaction.  Sound familiar?  It’s Newton’s Law of Motion.  I may be dumb but that guy was smart so you should pay attention.

Whats confuses the issue is that many people tend to fall down when they’ve been shot.  It isn’t caused by the projectile, they do it for all sorts of other reasons.  The belief that they are more seriously injured than they are, the “training” received by years of movies and television, or simply a desire to quit fighting all contribute.  Some people fall down when shot, some people don’t.  Since you can’t control it, you can’t count on it to happen during a fight.

Ok, so knock-down power can’t be achieved.  How do I stop my adversary?

The impact of bullets on the human body has four factors which contribute to how quickly an attacker is stopped.  The first factor is Penetration and is measured by the distance the projectile travels into the target.  The damage caused by penetration is directly related to the tissue disrupted or destroyed by the bullet passage.  The second factor is the Permanent Cavity and is measured by the volume of space once occupied by tissue that is now destroyed by the passage of the projectile.  This is the hole left in the guy after you shoot him.  The next factor is the Temporary Cavity and is measured by the amount of expansion or stretching of tissue due to the transfer of kinetic energy from the projectile.  The final wound factor is Fragmentation which are pieces of the projectile which separate and are propelled through the body.  Fragmentation may not occur in every bullet wound, and should be considered a secondary effect.  In fact, fragmentation in pistol rounds is extremely limited (typically less than one centimeter) and should not be heavily considered during bullet selection.

In order to quickly halt an adversary, the central nervous system must be severely damaged or destroyed.  For the anatomically challenged, check out the picture.

Notice the heart isn’t shown.  Shooting someone in the heart causes blood loss, perhaps major blood loss.  This will leave your attacker with approximately 15 seconds of full voluntary function before being incapacitated.  Fifteen seconds is a long time to have someone shooting at you.

In order to achieve fight stopping results, the brain or upper spinal cord must be severely damaged or destroyed.  This type of accuracy is clearly a function of training more than bullet selection.  The shot placement discussion occurs frequently, but it can’t be overstated how important marksmanship is to surviving a gunfight.

Bullet selection is critically important also.  Even assuming the accuracy is there, the bullet must penetrate enough into the target to pass through the central nervous system in order to achieve fight stopping results.  Because of this specific requirement, penetration is the most important factor in bullet selection.

Over-penetration gets talked about frequently in the law enforcement and self defense communities.  It’s true that a round can pass through the intended target and hurt a bystander.  It’s also true, and more likely, that a round will completely miss the intended target and hurt a bystander.  Misses are extremely common during violent assaults.  The risk of over-penetration should be carefully weighed against survival.  Over penetration might occur and a bystander could be injured, but a weak round will never quickly incapacitate an attacker.  When selecting a round for defensive purposes, a minimum of 12 inches of penetration is desired.  Anything less would be considered a poor choice.  More than 18 inches of penetration is probably unnecessary, but your situation should be carefully considered.  The round I select for my situation may be different than what is needed to meet your specific requirements.

Permanent cavity is the next most critical consideration when selecting a pistol caliber, or specific bullet.  The permanent cavity is the volume of destruction as the bullet passes through the target.  In this case, bigger is better.  Assuming an equal amount of penetration, a larger round will create a larger permanent cavity and will cause more damage.  Exactly how much “better” a larger projectile performs is extremely difficult to determine, and I won’t attempt to quantify it.

Temporary cavity is a much-hyped and misunderstood factor of projectile wounds.  Pistol rounds are underpowered by nature and relatively slow moving.  The latest research  on temporary cavity is that the tissue damage could be as small as one tenth of the speed of the projectile.  For the purposes of pistol gunfighting, it simply isn’t a factor.  If someone is trying to tell you how superior a particular round performs because of its “kinetic energy transfer” or temporary wound channel, you’re being sold a line of crap.

Fragmentation simply isn’t a factor for handgun rounds.  Pistol rounds move too slowly to achieve consistent fragmentation.  Again, since you can’t control it,  don’t count on it.  Fragmentation in a pistol fight is a non-issue.

The final characteristic I want to discuss is the idea of expansion.  Most of us have some experience with hollow-point ammunition.  The round is specifically designed to expand on impact to inflict greater damage to the target.  Assuming that 12 inches of penetration is achieved, an expanding bullet has lots of merit.  The problem is that hollow point ammunition has inconsistent performance.  When hollow point rounds impact bone, glass, or even thick clothing (it’s winter time), the round will expand very little, if at all.  Many times, forensics experts are unable to determine if a pistol gunshot wound was inflicted by a hollow-point round or a ball round.  Hollow point ammunition is certainly a good choice for a defensive round, but the performance in terms of penetration and permanent cavity should be used to assess performance.  Any expansion achieved will be gravy.

During the assault, you are in charge of very little.  Your attacker likely chose  the place and time.  He’ll control his actions, how many rounds he fires, and the tactics he employs.  You can control where your rounds impact his body and the type of weapon and ammunition you employ.

In order take control during an assault you must be trained.  If your training program doesn’t stress shooting on the move, shooting at moving targets, no-light engagements, and low percentage shots (partial targets), then you’re not preparing yourself to survive a violent assault.  It’s important to remember that you have to perform better than your assailant is lucky.
