Retired FBI agent on the pressure cooker and the victories of law enforcement

Stephanie Miller gets an inside look into the process of terror investigations from retired FBI agent Chris Kerr. He tells Stephanie that he’s surprised this kind of attack didn’t happen sooner after 9/11 and that it shows the “victories of various law enforcement agencies.” Stephanie asks if the pressure cooker implies anything. Kerr responds that it’s tempting to say it’s “a lone wolf or an unsophisticated group of people,” but a sophisticated group could have used this device to “throw investigators off the trail.”
