It's bad enough he did what he did, but then he posted it as a training video, encouraging others to watch.     Making him a failure at shooting safely and as an artistic director.

I certainly hope vsorrentino posts again, it happened, we caught it, we mentioned it, and it reminded us all that our love and passion for firearms, comes with NO margin of error when it comes to safety.

Always keep the gun pointed in a safe direction,
This is the primary rule of gun safety. A safe direction means that the gun is pointed so that even if it were to go off it would not cause injury or damage.
