Frontline's “To Catch a Trader”

Frontline correspondent Martin Smith talks about his documentary “To Catch a Trader,” which goes inside the government’s ongoing, seven-year crackdown on insider trading. It draws on video of hedge fund titan Steven A. Cohen, incriminating FBI wiretaps of other traders, and interviews with both Wall Street and Justice Department insiders. "To Catch a Trader" is airing January 7 at 10 pm on PBS.
