A Swiss magistrate has recommended that three members of a family in Switzerland be tried for violating their country's laws regarding the use and proliferation of nuclear weapons. Magistrate Andreas Muller told The New York Times that a six-year investigation by Swiss authorities showed Friedrich Tinner and his sons, Marco and Urs, were working with Abdul Qadeer Khan, the so-called ?father? of Pakistan's nuclear bomb. The Tinner family had also, according to American officials, worked secretly with the C.I.A. on nuclear issues since 2000. If the Tinners are found guilty, they face up to ten years in prison. But what does their relationship reveal about a black market of nuclear proliferation at work in a country so friendly to the U.S.?
