3) her child obviously got into her purse while she wasn't looking. Regrettable for sure, but it cannot be immediately labelled "irresponsible".
Why not? 'Scuse me, but if a parent's first responsibility is to keep their child safe from harm, this woman was woefully irresponsible. Her child is scarred for life, likely irredeemably. He killed his mother and will have to live knowing that he is responsible for that fact for the rest of his life. It beggars the imagination.
And I'd like to know why, every time one of these dumb-ass tragedies happen, we aren't supposed to point out the obvious stupidity of - well, in this case, a young mother shopping at Walmart with 4 small children - needing a f--king GUN in her handbag?
My despair is that a child of two years is now saddled with the weight of guilt and remorse that is beyond bearing. Because - freedom! Yeah, baby - gunz!
