He'd ask himself what, if anything, the cop could have done differently. But he also went beyond that, routinely coming up with alternate scenarios involving various twists on the factors in play: The number of cops or bad guys involved...what kind of firearms might be deployed...how the time of day or night might come into play...where he could exploit cover...how he could best direct resources to the affected location...
When he eventually got a job as cop in the Midwest, he continued the practice, and would in the middle of some windshield conference occasionally ask fellow cops how they planned for shootings. Sometimes, their answers took him aback.
"Now, what the hell would you want to talk about that for?" he'd heard more than once. "I don't want to dwell on that kind of thing"
The surprise he felt was matched only by his disappointment. Were there things that all cops hate to think about? Sure. But it never occurred to him that some cops would effectively take an ostrich approach when it came to the prospect of anticipating line of duty shootings.
My own curiosity spiked, I called other cops from throughout the country to see if they'd had similar experiences.
