Once upon a time a coach observed, "You play the way you train! You play the way you train!" Apparently he thought that if in general we trained appropriately with specific attention to each upcoming game/opponent, we'd get better on the field results come game day.
Maybe the problem with a low percentage of hits relative to shots fired by policemen stems from less than ideal training. And... maybe there's more to it. Policemen do not routinely shoot people. Many officers go their entire careers without drawing their weapon except at a range. Good for them. Police work is not a game. There is no score to be kept.
In the incident that recently occurred in NYC, some have opined that the policemen did a poor job of hitting the criminal. Oddly, he was hit many times. Maybe they should have just double-tapped him and then stepped back and looked to see if he cooperated by collapsing? Or... maybe under the circumstances they did about the best that could be expected from policemen who do not routinely slap leather and come up shooting at armed criminals at the Empire State building?
Perhaps it is a bit extreme to suppose that in each and ever instance where a police officer must fire his weapon that he will do everything exactly as a magazine pundit supposes is best, etc.
I've been thinking about this too, trying to come up with a theory. The training idea is a compelling argument, but how come among equally trained athletes, on a football field for example, some players perform better than others, or certain players seem to rise to the occasion when the game is in the balance? It might be something more than training, something intrinsic to the player that has nothing to do with training.
Also, I keep coming back to this idea that a policeman is at work, trying to earn a paycheck. It's not like he's in a situation where he's trying to protect the lives of loved ones. Maybe if a policeman was trying to protect his wife or children he might be a better shot. Maybe I'm reaching too much.
Still, I have to believe that there's more to performing well under stress than just training.
