This photograph was taken soon after the soldiers ceased firing. This picture also proves that the soldiers' lives were not in imminent danger at the time they fired. Nobody is nearby, except for the few who are tending a wounded student.
Only five soldiers admittted to firing on the students. If they were all honest, those five soldiers killed four persons, wounded nine others and shot more than thirty bullet holes into parked cars in the lot.
I think they deserve a medal or something for their marksmanship.
