Happens quite a bit. Some guy shot his daughter like that on the west coat last year I believe. Parents leave the house for anniverary dinner.
She sneaks into the house to leave a gift in their bedroom. Dad while pulling out of the driveway notices shadow through the window. Grabs his 44 Mag from the glove box. Stops the car, re-enters the house. Daughter hears him, hides in the bedroom closet with the gift, planning to surprise him. He comes into the room gun drawn, she jumps out of the closet, yells surprise with huge smile on her face and gift in hand. He put one in her chest. She died in his arms. Again you own a gun doesn't mean you have to stick your toothbrush in the barrel and brush your teeth like that. Someone breaks into my house , I am flipping the lights, and choking them out. It's more fun like that anyway. Home defense doesn't mean just gun. All some people know is gun, gun, gun! You take the gun away and there is nothing left. Total pussies! Well you better cling to that gun then.
