Didn't anybody warn Congressman Jefferson not to respond to those Nigerian emails?

"Nigerian officials say the bribery investigation of Congressman William Jefferson (D-La.) has uncovered a massive corruption scheme involving several members at the highest levels of the Nigerian government.

Acting on information provided by the FBI, Nigerian fraud investigators have now indicted Vice President Atiku Abubakar on 14 counts of corruption, involving tens of millions of dollars allegedly diverted from government accounts."
