The New York Police Department is doing everything it can to make sure there’s not another 9/11 here and that more innocent New Yorkers are not killed by terrorists,” NYPD spokesman Paul Browne said. “And we have nothing to apologize for in that regard.”
In the months after 9/11, the FBI deployed its investigative apparatus as a blunt weapon. In November 2001, the Department of Justice began conducting “voluntary interviews” with 5,000 Middle Eastern non-citizens. Hundreds of FBI agents were dispatched across the country to conduct the interviews, with standard questions like “Are you aware of anybody who reacted in a surprising way about the terrorist attacks? Maybe you got to work and maybe a coworker said, ‘Good, I’m glad that happened’?”
