Of course it was willful negligence: many people knew that Hasan was a jihadi, but political correctness and fear kept them from doing anything about him. “Victims, Family Seek $750M For Fort Hood Tragedy,” from The Associated Press, November 10 (thanks to Kenneth):
More than 80 victims and family members in the worst-ever mass shooting at a U.S. military installation are seeking $750 million in compensation from the Army, alleging that willful negligence enabled psychiatrist Maj. Nidal Hasan to carry out a terrorist attack at Fort Hood, Texas.
The administrative claims filed last week say the government had clear warnings that Hasan, who is scheduled to go on trial in March, posed a grave danger to the lives of soldiers and civilians.
The victims and family members allege that the government bowed to political correctness and not only ignored the threat Hasan presented but actually promoted him to the rank of major five months before the massacre two years ago that left 13 dead and more than two dozen wounded.
