AN AMERICAN STAFF SARGEANT IN IN SOLITARY CONFINEMENT IN LEAVENWORTH PRISON FOR ALLEGEDLY KILLING 16 AFGANISTAN CITIZENS.  HE IS FACING LIFE IN PRISON OR THE DEATH PENALTY.  HE WAS ON HIS FOURTH TOUR OF DUTY.  THIS WOULD BE AN EXCELLENT TIME FOR THE DEPARTMENT OF DEFENSE TO RE-EXANINE THEIR POLICIES ON THE NUMBER OF TOURS ALLOWED.  PERHAPS THIS IS A PRIME FACTOR IN BRINGING ABOUT SUCH KILLING.
