Three-time Olympic swimming champion Sun Yang's career was in tatters on Tuesday after the Court of Arbitration for Sport's suspension for refusing to give a sample to doping inspectors. He was handed a ban of four years and three months for violating anti-doping rules. Beijing residents react to the decision. "If he really believed in his own innocence, he should have just let them (get his sample)," says one resident while another says: " I feel very sorry for him…I hope he can come out of this incident well."
