Pistorius - he should not be able to run at the Olympics

I disagree stongly with Lausanne's sporting tribunal decision allowing South African disabled runner Pistorius to run against able bodied athletes at the Beijing Olympics. With no disrespect to Pistorius, it is impossible to determine whether the carbon fibre blades he wares actually give him an unfair advantage against able bodied athletes. As a result, he should be restricted to competing in the Para Olympics where such prosthetics arae allowed.
