The New Yorker reports Chinese paper Southern Daily claims they've seen surveillance footage of Sun Danyong's interrogation by Foxconn, which show that he wasn't locked up or tortured. It also says that Sun told Foxconn to search his house.
The latter report is the more interesting of the two, for the glimpse it gives into Foxconn's corporate culture: When Foxconn security manager Gu Qinming interviewed Sun, he says that Sun initially blamed the missing phone on a female colleague, provoking Gu to poke him in the shoulder and ask, "Are you a man?"
According to Gu, it was Sun who suggested that Foxconn search his house, to prove his innocence. Which almost sounds reasonable, insofar as Gu thought Sun was both incompetent and a liar—what else could Sun have done?
Yet, Sun was quoted as saying on a Chinese message board, "Even at a police station, the law says force must never be used, much less in a corporate office. I was just a suspect, my dear head of security, so what reason and right do you have to confine me and use force?"
Keep in mind as well that the latter report is based on the word of the guy who interrogated Sun Danyong before his death and works for a company so secretive it might have driven a man to suicide over a phone. [The New Yorker]
