Fact check
Is it true: JFK Assassination: Second Shooter from the Grassy Knoll?
There's no solid evidence for it.
The grassy knoll second-shooter claim rests primarily on acoustic analysis of a Dictabelt police-radio recording (basis for the HSCA 1979 "probable conspiracy" conclusion). The NRC (1982) and FBI independently rejected the acoustic evidence, finding the identified impulses were recorded after the assassination. No physical evidence of a second shooter (no bullet, no shell casings, no firing-position evidence) has been recovered. Witness testimony is genuinely mixed but insufficient to establish a second shooter. Unsubstantiated but not fully resolvable.

Key evidence
HSCA 1979 concluded probable conspiracy based on acoustic evidence
NRC (1982) rejected the acoustic evidence entirely
