After winning the Pulitzer Prize for Investigative Journalism for their reporting on the NYPD's surveillance of Muslims after the attacks of 9/11, Adam Goldman and Matt Apuzzo stop by to discuss counter-terrorism efforts that work, and those they find to be counter-productive. Both are AP investigators and authors of the new book Enemies Within: Inside the NYPD's Secret Spying Unit and bin Laden's Final Plot Against America.
