Did Lee Harvey Oswald really kill President Kennedy?
I see. What about the grassy knoll and the mysterious woman in the polka-dot dress?
The grassy knoll and the mystery woman in a polka-dot dress are two popular theories of the assassination. Some witnesses claimed that they saw someone firing shots from the grassy knoll, while others saw a woman in a polka-dot dress running away from the scene. However, these theories have never been fully substantiated.
