"Zero Dark Thirty" took just one minor award at the Oscars last night. There was a lot of debate about the way the film depicted torture during the hunt for Osama bin Laden.

Turns out that wasn't the only controversy.

The film starts with actual voices of victims of September 11, recorded as they made their last phone calls. For Mary and Frank Fetchet, it brings back painful memories. One of those voices was their son Brad, who worked on the 89th floor of the World Trade Center's South Tower.
