Oswald didn’t do it ,, there was a bullet hole in the windshield indicating a shot from the front... also plenty of audio evidence for multiple shooters. Secret Service and Dallas PD only parties that knew of the visit with enough warning to organize an op.
We did one of the Sore/Loserman events in Dealey Plaza, the echos were impressive.
There was no bullet hole in the windshield, but there was a dent on the INSIDE of the metal trim around the windshield, indicating that fragments from BEHIND hit it. There were cracks too, on the inside of the glass.
