Interesting that you bring this up JLaw. I have it as a test question on the final exam for our academy students on Friday. And the correct answer on the test is that it means the center of the largest part of the target that is visible to you.
I explained it in class as meaning the big toe, if that is all that is visible for you to shoot at. We also set up some targets with others partially blocking them to show how the COM can change.
And, TX Rancher, I agree with the other posts you got except for one. I was taught that shooting to stop is the explanation of how we shoot to stop a person from being a threat. You can keep shooting until you do stop the threat, which is why the term used for the Mozambique and similar drills is a failure to stop drill. Some police agencies/trainers still call it the body armor drill, but most are going to the failure to stop term.
The post I disagree with is the one that says killed = stopped. While I do agree that a person killed is eventually stopped, it does not always happen immediately (reference the Miami shootout where a man suffered a non-survivable wound and kept fighting long enough to kill or wound six FBI agents). Also, the reverse is not true. Stopped does not always mean killed. As was posted, if they run away at the first sight of the gun, you have stopped the threat without shooting. If they run after the first shot, you stopped the threat and stop shooting.
