USA : gunfire on the campus | M6 | 66 minutes

A shock report from the United States, six days after the Virginia Tec shooting leaves 32 dead.

Why such madness? The killer was a lonely, disturbed student. He had already been spotted by psychologists who considered him dangerous. How was he able to get firearms with no problem? An on-the-spot investigation with eyewitness accounts from survivors.
