If there were shots fired by someone prior to the NG volley, I'd bet a cup of coffee they were fired only to 'trigger' the NG in an effort to make them "chain" fire.
Based on this:
It also turned out that the FBI had its own informant and agent-provocateur roaming the crowd, a part-time Kent State student named Terry Norman, who had a camera. Mr. Norman also was armed with a snub-nosed revolver that FBI ballistics tests, first declassified in 1977, concluded had indeed been discharged on that day.
It would seem to me, if someone went back there and meticulously searched for spent rounds ((long shot) no pun intended, they could break this case if they got really lucky...That is if the Feds still have the revolver in some evidence property room.
No doubt these rounds were searched for, but it would not be the first time evidence went undiscovered.
I'm not say, I'm just sayin.
I agree. One of the articles I read did seem to mention rounds found behind the NG. Two instances of munition impacts were addressed.
