Zyzanski was home with three friends when he decided to show off a shotgun he had. Given his 2008 felony conviction for aggravated discharge of a firearm, this alarmed his friends. When the friends asked him to put the firearm away he said that they had nothing to worry about. Zyzanski proceeded to rack the slide several times, ejecting two or three shells and decided to show his friends it was safe and empty.
He then held the gun to his face and pulled the trigger. It went exactly how you think it did.
Let's review the four rules of firearms safety as written by Col. Jeff Cooper (plus a bonus fifth rule for those playing along at home) and see how Zyzanski did:
RULE I: All guns are always loaded. Fail.
RULE II: Never let the muzzle cover anything you are not willing to destroy. Fail.
RULE III: Keep your finger off the trigger until your sights are on the target. Fail.
RULE IV: Know your target and what's beyond it. Undetermined.
And our bonus rule for the home edition:
RULE V: If a felon brings out his cool new shotgun to show you and his friends. Get the hell out of there. Fail x 3 friends.
