Too bad he couldn't have shot himself so he wasn't such a danger to others
The first thing you are taught when you get your license is that you NEVER POINT YOUR GUN near ANYONE. Loaded or unloaded, safety or no safety. Your finger should not even be near the trigger and the gun should not be loaded unless you are ready to fire.
Guns are not toys, but like cars or chainsaws some idiot like this will manage to harm others and even his own family due to idiocy. He should face prison time
