An line of grim-faced Russian mourners almost a mile long waited to pay their respects Tuesday to the most prominent opposition figure to be murdered during President Vladimir Putin's rule. Well-wishers clutched flowers as they lined up outside the Sakharov Center in eastern Moscow where Boris Nemtsov's body lay in state. "Boris Nemtsov stood for the best in Russia," said American Ambassador John Tefft as he delivered condolences from "the president and from all the American people."
