Apologies for getting the thread off topic...just to clarify:
When blocking a "right hook" type punch in an upstage downstage type scenario (like in a proscenium theatre), you have to aim at the face of the person, also called the ZMD, Zone of Maximus Destruction. Your fist is 12-16 inches away from their face, as well as an understanding between the two combatants. Aim and accuracy is important, otherwise it's sloppy and dangerous.
And the firing the weapon, I am aware of not firing it directly at a person and am quite familiar with the "Crow" story. The specifics of my story, which I should have included, were when working on Les Mis, an actor unconvincingly fired the gun. It was supposed to be pointed at a specific target against a wall, and he fired it towards the ground, without miming the correct kickback or holding it properly. These were cap-gun type rifles, no ammunition. It took a few rehearsals to teach him how a real rifle would fire.
Again, apologies to the forum for the bit of lash-back that was created by my post. Got to be more specific next time. Thanks and appreciation for the discussion on safety everyone.
