It seems some of the soldiers responsible for our safety and security are going stir crazy -- and turning their guns on themselves.

Very reassuring.

ATHENS, Aug 23 (Reuters) - A Greek soldier guarding an Olympic facility in Athens was shot dead on Monday after apparently playing game of Russian roulette with a policeman, security sources said.

Greek police were questioning a policeman in connection with the pre-dawn shooting at the gates of an Olympic village hosting escorts to Olympic teams in the Metochi Parnithas region of Athens.

It appeared that a prank had gone wrong while the pair were playing with a service revolver containing a single bullet, the sources added.

The 25-year-old soldier was shot in the forehead.
