I recall a diagram in evidence that traced the trajectories.

That is still speculation without recovered bullets and confirming ballistics. Given the released information that other shooters were present, you don't know whose bullets actually hit the students.

Are you going to tell me some of the hippies was carrying a 30-06 so they match the ballistics to the National Guard?
