A Hurdler's Pain

It seems like there are mixed reactions (disappointment, anger, disbelief, etc) to Liu Xiang's injury (as seen in the NYTimes video). But, the one response that really bothered me was the gentleman who said Liu Xiang was faking it and that he was afraid to lose his prestigious status in the hearts of many if he got a silver or bronze. It's incomprehensible to me first why someone like him would fake an injury, knowing all Chinese eyes were on him. And secondly, why someone would think he was faking it. Jeez, give the guy a break.
