If teaching a class, Police/Security/ or CCW, sitting a manikin, no arms or legs, on a table. Shows by pointing, and giving a guess, on where that round might go. As in what organs sit behind the impact point.
I say might, because from a pistol, bones cause deflection, or even where you aimed, the person moves, that shot has now changed.
Seems to me, just my opinion, that firing once, then pausing to see what happens now, is not too bright, and shooting multiple times at an aggressor, can sometimes produce no discernible result, that if, or when, you get in a shooting war with a single individual, your conflict is going to be yours, and yours alone.
Like the song says "What ever will be, will be"
