The YouTube Gunman

Just 24 hours after 22-year-old Matti Saari was questioned by police after he posted a disturbing YouTube video and released because he had the proper gun license, he went to a school and opened fire on students:
Saari uploaded disturbing footage onto YouTube of himself practising at a firing range and turning to the camera to proclaim: ‘You will die next.’
Worried police interviewed the second-year domestic science student about the clips - but, because he had an appropriate gun license, did not take him into custody.
Just one day later he stormed into an exam hall and opened fire with an automatic weapon before killing himself.
