My personal theory is the KGB it. When Oswald visited Minsk, the Russians killed him and sent a double to whack the president..
When I was at UT Austin Oswalt’s daughter lived down the street.
Look for paragraph saying surgeon general report said two shooters
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.
