The death itself is senseless, Barsel. The parents are reckless, careless, brainless - choose any or all. Not only will the kid now have to grow up without a mother, he will one day learn that it was he who killed her:-(
Its not the gun ownership thats the problem (many countries own guns especially large ones with hostile environments) its the owners. Unfortunately the good old US of A does seem to have more than its fair share of dolts.
