Exactly. We were always told, to shoot to stop the threat, but once the threat stopped, the shooting stopped too. While these dudes were shucking and jiving, it would be almost impossible to hit them at all, let alone, to wound them. If they “moved,” as you say, we needed to articulate it in great detail. They ALWAYS moved. 😁
We were taught to shoot center of mass, but with a moving target, who knew where that bullet would end up. Head shot? Oops, he moved.
