Why?

Maybe my posts have been a bit darker than usual lately, but sometimes things happen that are just so.... awful. Did you hear about Gabrielle Giffords getting shot the other day? She was talking to people at a Safeway in Tuscon, Arizona when a man came and shot her through the head. After she was down, he fired on civilians. Why? He ended up killing three older people, a federL judge, and a nine-year-old girl named Christina. Why? It's one thing to go and shoot your target, but it's a whole nother thing to shoot standers-by. I'm NOT saying that it's okay to shoot people, that's horrible, NEVER DO IT, but it's even worse to kill innocent people who just happened to be in the wrong spot. A nine-year-old. She had her whole life ahead of her; why?
