The court-martial for an Army major accused of killing 13 people during a rampage at Fort Hood, Texas, opens today at the same base where the attacks took place in 2009. Major Nidal Hasan has won the right to represent himself in court, meaning he will likely question some of the same people he is accused of attacking. Judge Tara Osborn has already struck down Hasan’s planned defense that the shootings were an attempt to protect Taliban leaders in Afghanistan from U.S. soldiers. Hasan is charged with 13 counts of murder and 32 counts of attempted murder. He could face the death penalty if convicted.
