Thursday marks 30 years since the release of 52 American hostages who were held in the US embassy in Tehran for 444 days by a group of Iranian students and militants. Barry Rosen was one of those hostages. He worked as a press attaché in the embassy in Tehran, and he says the anniversary of his release remains fixed in his mind. "I have to remember it," Rosen says. "If I had a place to go, I would go and stand there. But I don't have a place to go."
