Introduction

You live in a society deeply conflicted about police violence. Headlines condemn officers for using lethal force, while public demand for protection remains high. You likely wonder what actually happens in the moments before an officer pulls the trigger.

David Klinger cuts through this public debate using firsthand police experience and scientific research. He examines the minds and actions of officers who have shot citizens in the line of duty.

Police officers enter deadly environments with extreme reluctance, exercising profound restraint and relying on strict tactical training and mental preparation when forced to use lethal power.

The book explores several core questions:

  • What drives individuals to join the police force?
  • How do academies prepare officers for deadly encounters?
  • Why do officers hold their fire in dangerous situations?
  • What happens psychologically and physically inside a real gunfight?

1. Entering the Kill Zone

David Klinger brings direct firsthand experience as both a police officer and an academic sociologist to the study of police-involved shootings. You see that he worked as a patrol officer for the Los Angeles and Redmond Police Departments for three and a half years. During that time he was involved in a fatal shooting, before pursuing graduate degrees and becoming a criminology professor.

Prospective police officers enter law enforcement through various motivations and backgrounds while confronting public misperceptions and deep societal ambivalence about lethal force.

The psychological toll that shootings take on police officers reflects a broader societal ambivalence about granting the state the power over life and death. Society demands protection from criminals and empowers the police to use lethal force on its behalf. Yet you find that citizens simultaneously fear for their freedoms and demand that officers use this awesome power judiciously and grudgingly.

The underlying research for the book is derived from in-depth interviews with a large cohort of police officers who experienced shooting incidents. The author conducted extensive tape-recorded interviews with 80 men and women law enforcement officers regarding their experiences before, during, and after stepping into the kill zone. This research received award number 97-IJ-CX-0029 for National Institute of Justice research funding.

Popular Myths and Realities

Popular media portrays policing through shallow or wildly inaccurate myths. You enter law enforcement unaware that actual shootings are rare events unless you learn otherwise from family or friends already on the job. Prior to joining the force, ordinary citizens share the general public's misperception that officers shoot people regularly.

American legal and civic morality strongly enforces the sanctity of life through the norm against killing. Rooted in the biblical injunction against killing, society maintains a sweeping norm that taking life is wrong. You face a psychological hurdle that future officers handle in vastly different ways before being hired.

David Klinger killed a man in July 1981 while working as a young police officer at the 77th Street Division of the LAPD to save his partner's life.

Pathways into Policing

Law enforcement agencies actively screen applicants during hiring interviews by directly asking if they believe they could kill someone if necessary. Knowing that some individuals lack the psychological capacity to take a life, hiring boards use direct interview questions to test an applicant's willingness and readiness to use deadly force. An officer interviewed by the author recalled being asked by the oral board if they could take a life, which was their first introduction to the reality of shooting someone.

Military experience, particularly in combat or specialized reconnaissance units, often serves as a direct bridge into law enforcement careers. Veterans transitioning to police work frequently cite the structured paramilitary environment, tactical training, and familiarity with high-stress situations as key factors in their career choice.

An officer who served as a combat medic in Operation Bright Star and later witnessed a violent drug deal shooting during a ride-along decided policing matched his military background. That veteran had completed a two-year hitch in the army and 90 credit hours before joining the department.

2. Training for the Ultimate Test

Police academies instill strict legal standards, tactical force continuums, and mental rehearsal techniques that condition officers to stop threats rather than kill.

Legal and Tactical Standards

Federal law sets the outer bounds of police firearms use via the defense of life doctrine. This standard permits deadly force strictly for defense against fatal or injurious attacks, shifting the legal parameters away from previous allowances. In 1985, the United States Supreme Court ruled in Tennessee v. Garner that shooting fleeing nonviolent felony suspects is unconstitutional.

Police recruits are taught that the purpose of deadly force is to stop an illegal act rather than to cause death. Officers are trained to discharge their firearms only as long as a suspect presents an imminent threat or attempts to flee, ceasing fire once the threat ends. The lethal outcome is a byproduct of aiming for center mass to ensure accuracy, not the intended goal.

Police academies instruct recruits on a force continuum that prioritizes verbal commands and defensive tactics before resorting to deadly force. Recruits learn that deadly force is the absolute last option. Training includes extensive hours on empty-hand techniques, defensive tactics, and nonfatal force to manage situations without firearms. One officer noted receiving twenty classes comprising eighty hours of arrest control and defensive tactics.

You navigate the force continuum through these steps:

  • start with the spoken word;
  • progress to empty-hand techniques and hand-to-hand combat;
  • use minimal weapons like mace or a canine;
  • utilize impact weapons like the nightstick;
  • resort to deadly force only as the absolute last option.

Mental Preparation

Instructors emphasize running through mental scenarios, playing out potential threats, and preparing responses in advance. This conditioning allows officers to draw from memory and react quickly without having to solve complex tactical problems under extreme stress. One veteran officer routinely created mental what-if games regarding vehicle stops, weapon displays, and tactical positioning to ensure readiness.

You can apply the mental-preparation class methods on your own:

  • look at incidents that have happened within the department or realistically could happen;
  • run through your mind what you would do in those particular situations;
  • condition yourself to go to cover, return fire if necessary, change positions, and reload;
  • cover follow-up procedures such as what to say on the radio, preserving the scene, and rendering first aid.

Exposure to officer-involved shootings, murders of peers, or severe injuries forces young officers to confront the dangerous reality of their profession, altering their expectations and sharpening their survival instincts. An officer working the midnight shift experienced a severe reality check when their sergeant was murdered by burglary suspects at the Westpark Shopping Center. That murder case took three years to resolve, and a month and a half elapsed before another officer was shot following the sergeant's murder.

3. Holding Fire on Patrol

Written rules state only that you may use deadly force, not that you must. Because legal and administrative standards are broad, you develop stricter personal shooting policies during your apprenticeship.

Officers exhibit substantial restraint and hold their fire in the vast majority of instances where their lives are threatened.

During police academy training, the author personally adopted a rule that he would not shoot fleeing suspects. Historical studies and interviews reveal that officers shoot in only a fraction of cases allowed by law. Out of eighty interviewed officers across four major cities, sixty-eight reported holding their fire in potential shooting situations. About twenty officers held back in five to ten cases, and a few highly active officers reported thirty or more held-fire situations.

Patterns of Restraint

Veteran officers distinguish between legal justification, moral justification, and actual necessity when deciding whether to pull the trigger. Even when you have full legal authority to use deadly force, you exercise forbearance if the situation can be resolved without it.

A veteran SWAT and narcotics officer with over twenty-five years of experience noted that he held his fire in about two dozen cases where he was legally justified. His dedicated narcotics raid team executed about 250 a year over four years without unnecessary force.

Patrol and SWAT Realities

Patrol work accounts for the largest share of police contacts and generates the highest number of near-shooting close calls. You frequently manage tense encounters involving unarmed people simulating weapons, knife-wielding individuals, and erratic gunmen without resorting to deadly force.

An officer in the Tritopolis area faced a suicidal man backed against a fence holding a knife to his stomach. The officer maintained a comfortable distance of twelve to fourteen feet, well under the recommended twenty-foot distance to keep from someone wielding a knife. Each time the man advanced, the officer chose to retreat rather than shoot until the man finally stabbed himself slightly, dropped the knife, and stopped.

Frontline patrol officers often enter situations with minimal information and must make split-second decisions. You must constantly factor in the possibility that seemingly threatening individuals posing with weapons are actually crime victims or fellow officers.

An officer on probation twelve to fifteen feet away nearly shot a Hispanic man holding a cocked .45 automatic at a forty-five-degree angle, but held fire at the last second upon realizing the man was distraught because a burglar had just stolen his car radio.

4. Inside the Gunfight

When deadly force becomes unavoidable, engagements occur at close range amid severe perceptual distortions, weapon retention struggles, and extreme physical trauma.

Dynamics of Close-Quarters Shootings

Most real-life police shootings occur at very close range and involve officers firing only a small number of rounds in a matter of seconds. Fictional portrayals often place officers far from targets. Actual engagements typically happen at a separation of a few yards or less. Furthermore, officers usually fire fewer than a handful of rounds within a second or two.

A rookie officer fired only two rounds and his partner fired four at a robber who was shooting at them from the middle of a four-lane street. The suspect fired nine rounds and officers fired thirteen total in that rookie's first shootout.

Officers are legally permitted to make good faith mistakes in their use of deadly force under the standard of reasonable belief. The rules governing deadly force do not require an actual deadly threat to be present, only a reasonable belief by you as the officer. This can lead to mistakes such as shooting individuals wielding toy guns or unarmed people whose actions immediately prior led to the reasonable belief they were armed. Such errors differ fundamentally from malicious unlawful shootings, and only three of the author's interviewed officers shot unarmed individuals.

An officer shot a suspect who was pulling a replica Colt .45 BB gun from his waistband during a car burglary attempt.

Attempts by suspects to disarm police officers represent a lethal threat, as a significant minority of shootings occur during such struggles. Suspects frequently attempt to take officers' weapons, and those who succeed often shoot the officer shortly after. Just under 10 percent of officers murdered with firearms in the decade ending in 2000 were slain with their own guns.

An officer named Mike was kidnapped and held hostage with a gun to his head after a suspect disarmed him during a foot pursuit.

Survival and Psychological Responses

Life-threatening encounters frequently trigger extreme perceptual distortions, including tunnel vision, slow-motion perception, and auditory exclusion. Officers involved in intense gunfights routinely report that time seemed to slow down, sounds of gunfire were muffled or unheard, and their visual field narrowed exclusively to the threat while surrounding details vanished.

During a shootout, a rookie observed his front sights and wondered why the suspect wasn't falling, while failing to hear the loud gunshots, perceiving them instead as soft pops.

When a firearm malfunctions during a critical incident, operators must execute an immediate remedial action drill to restore functionality. The drill clears jammed rounds or failure-to-fire conditions so you can re-engage the threat without delay.

An off-duty officer working security at a bank experienced a loud click when his gun malfunctioned and executed the tap, rack, and shoot drill to get back into the fight.

Use this sequence during a weapon failure:

  • Tap the magazine
  • Rack the slide or charging handle
  • Shoot the target

Intense mental determination and the will to survive can sustain officers through catastrophic physical trauma and multiple cardiac arrests. Officers suffering severe organ damage, massive blood loss, and clinical death on the operating table have demonstrated that fighting spirit and external encouragement from loved ones can aid recovery.

An officer spent two days unconscious in the hospital before waking up after being shot through the chest by a .357 Magnum. He suffered a lacerated heart, flatlined multiple times, endured emergency open-heart surgery without anesthesia during a second cardiac arrest, and ultimately recovered.

Conclusion

Rigorous training, personal forbearance, and psychological resilience shape the harsh reality of police shootings, proving that lethal force is used with extreme reluctance rather than casual abandon. You can apply these hard-earned lessons from street-level gunfights to understand high-stress encounters and maintain control when survival demands it.

  1. Recognize that lethal force is always a last resort governed by the strict criterion of necessity.
  2. Rely on rigorous tactical training and muscle memory to guide your actions when perceptual distortions strike.
  3. Maintain extreme forbearance on the street, holding your fire whenever a suspect shows willingness to comply.
  4. Prepare your mind for the profound psychological and physical trauma that follows any unavoidable use of deadly power.
