Accomplishing such self-control demands realistic expectations of the officer. Unfortunately, many cops are not so grounded.
"Most police officers have never been involved in a shooting," notes Dennis. "If your frame of reference is what you see on television, then your perception is very much altered—for the worse. And if an officer's perception is flawed, then his fear will most likely be disproportionate or inappropriate."
Dennis, author of "
Officer Down: A Practical Guide to Surviving Injury in the Street
," says that a compromised mindset can exacerbate the fear naturally inherent in a shooting, and also undermine the officer's physiologic response to it, compromising nature's mechanisms for responding to fear and/or injury—heart rate, blood pressure, and breathing rate—from operating at maximum efficiency. Such are the reasons that Dennis cautions against allowing yourself to suffer from a disproportionate fear should you be wounded in a firefight.
"All of these things culminate in your overall reaction or response which is defined as your decisions and actions," counsels Dennis. "As opposed to training with a true understanding with a strong frame of reference, an accurate perception, ultimately that leads to allowing one to keep their fear in check, limit their degree of fear, or have control over their fear, and their mindset is strong, their physiological response is appropriate and proportionate, and ultimately their decisions and action are better. That is the most important thing when it comes to understanding injury and shootings."
Of course, just retaining one's consciousness—let alone lucidity—can be a heady proposition. When civilian Kenny Vaughan was shot about 20 times outside his home in 1995, he refused to close his eyes. "I kept telling myself, 'If you close your eyes, you'll go into shock and you're dead.'"
