I'm reminded here of the case of Carroll Walker, An archer who lost an arm and rehabilitated himself by learning to draw the bow with his teeth. After a few years of practice he had achieved an amazing degree of accuracy. He was easily able to outshoot able-bodied archers. When he was tipped for the Olympics he was unable to go as the Committee decided "The method of drawing employed is not consistent with that expected for an olympic competitor" Obviously the same double standard applies to Pistorius and by extension to any disabled athlete who wishes to compete with the able-bodied. Hardly an incentive?
