Last summer, as three UC Berkeley graduates accidentally wandered across the border into Iran, they stumbled into a country with two American armies on its borders, a rush to develop nuclear weapons seemingly at any cost, and its own velvet revolution threatening to topple the hoary old mullahs. That's hardly a formula designed to expedite their release. But now, the families of the three adventurers have hired an international attorney known to get results from the theocratic regime. According to the San Francisco Chronicle, attorney Masoud Shafii helped in a case in which Iran charged two of its own physicians, who specialize in AIDS treatments, with trying to help the United States undermine the Iranian government. Now, he's working with the families of the three imprisoned Americans.
