The US Was Warned

This just makes me angry:

The terror suspect who tried to blow up a Detroit-bound plane is the son of a Nigerian banker who alerted U.S. authorities to his "extreme religious views" months ago, it was reported Saturday.

The father, Alhaji Umaru Mutallab, a former minister and chairman of First Bank in Nigeria, is shocked that his son was even was allowed to fly to the U.S., family members told the Nigerian newspaper This Day.

Who was the government official who was warned? Why was this loon allowed on a flight to the US? Here's a simple test for the Obama administration: find the people responsible for this negligence and fire them.
