NOMAAN MERCHANT, PAUL WEBER, Associated Press FORT HOOD, Texas —
The military trial of an Army psychiatrist accused in the 2009 shooting rampage at Fort Hood has started under heavy security at the Texas base. Maj. Nidal Malik Hasan on Tuesday entered a military courtroom on charges of killing 13 people and wounding 32 others. Hasan doesn't deny committing one of the worst mass shootings in American history but was forbidden to plead guilty under military law. That's because Hasan faces the death penalty — a rare punishment in the military. The last execution in the U.S. military justice system was 1961. A long row of shipping freight containers, stacked three high, created a makeshift fence around the courthouse on the first day of the trial. The trial is expected to last several weeks.
