A year after a Nigerian man allegedly tried to blow up a Detroit-bound
airliner, officials say they have made it easier to add individuals'
names to a terrorist watch list and improved the government's ability to
thwart an attack in the United States.
The failure to put Umar Farouk Abdulmutallab on the watch list
last year renewed concerns that the government's system to screen out
potential terrorists was flawed. Even though Abdulmutallab's father had
told U.S. officials of his son's radicalization in Yemen, government
rules dictated that a single-source tip was insufficient to include a
person's name on the watch list.
