MONTE CARLO, Monaco (AP) - All his life, Oscar Pistorius has confronted obstacles. The double-amputee sprinter from South Africa now faces another one a decision barring him from the Olympics. Track and field's governing body ruled Monday he is ineligible to compete this summer in Beijing or any other sanctioned able-bodied competitions because his "Cheetah" racing blades are "technical aids" that give him a clear advantage. "He has been competing in South African able-bodied competition for the past three years," Van Zyl said. "At this stage it looks like he is out of any able-bodied event." http://msn.foxsports.com/olympics/story/7658380?MSNHPHCP>1=10838 Fair or not fair?
