On Christmas day in 2009, Umar Farouk Abdulmutallab failed to detonate an explosive device he hid in his underwear, while flying aboard Northwest Flight 253 to Detroit, Mich. Abdulmutallab pleaded guilty in court yesterday to all eight charges against him, including conspiracy to commit terrorism, attempted murder on an aircraft, attempted placement of a destructive device, and the attempted use of a weapon of mass destruction. Quinn Klinefelter, senior news editor at WDET in Detroit, talks more about the trial.
