We. Are. Not. Trained. To. Wound.
We are trained to stop the threat.
Please don't spill undocumented opinions if you are not on the blue line. And don't throw in fancy words like "marksman" without knowing how they're used within agencies. "Marksman" can refer to someone who achieved the highest possible score in handgun training just as well as we can talk about a "sniper marksman." And the two are absolute opposites.
Furthermore "police" can refer to a multitude of agencies that train differently. There's RCMP, CN Police, local / municipal police agencies and so on. However, regardless of who trains the officer, I can't emphasize enough: we are trained to stop the threat.
Someone mentioned "under duress." There are a multitude of factors involved in use of lethal force (i.e. drawing a sidearm and making use of it) ranging from having given chase to tunnel vision to multiple threats to prioritizing to who's behind the threat (am I hitting innocent bystanders?) and the list could go on. This is what "duress" means and it's still an understatement. Some officers can't even pull their gun, and would rather get hurt than taking another life. Training and real life are very different things.
But back to the point, let's agree for "centre of mass" as the main focus point of our training. I can't comment on the specifics of my agency, suffice to say whoever comes with such nonsense as "trained to wound" has no bloody clue what they're talking about.
Finally, if the person being so knowledgeable about police procedures means "less than lethal" weapons, (s)he may refer to CEWs (Conducted Energy Weapons aka "tasers") or batons / chemical agents aka "pepper spray". That doesn't kill indeed, but it's not guaranteed to be effective either (some subjects have high pain tolerance or capsaicine simply doesn't work on them.) I don't know if I wanted to "pepper-spray" a subject that comes to me with a machete, rather than using a more effective means of stopping him. At the end of the day, I am paid to do my job, I am trained to do my job, but I also want to get back to my family in one piece. So there's that... "Better judged by 12 than carried by six."
