The other day, star South African athlete Oscar Pistorius shot and killed his girlfriend, Reeva Steenkamp. Born without fibulas, Pistorius inspired his nation and the world, as he ascended to the highest levels of sport, competing in the Olympics and Paralympics on prosthetic limbs. He claims that the shooting of Steenkamp was a tragic mistake: that he thought she was an intruder breaking into his home. That's his defense. You believe him? Personally, I don't think he has a leg to stand on.
Oh, like you weren't thinking it!
(And before you condemn me, may I point out that MOS's initial comment was, "I don't think his defense has legs." So you see where I get it from.)
