The Grassy Knoll

Witnesses ran toward the fence, not the depository. The acoustics said four shots.

The acoustic evidence (a police dictabelt) drove the HSCA's 1979 'probable conspiracy' finding of a fourth shot from the knoll; the National Academy of Sciences' 1982 review (Ramsey panel) found the analysis flawed — crosstalk dating the relevant sounds after the shooting. Fifty-plus witnesses reported shots or smoke from the knoll area (documented in Warren volumes); photographic analysis (Moorman, Zapruder) remains contested. The node holds the specific evidentiary fight, distinct from the general JFK file: one hillside, two federal conclusions.
