When the FBI arrived they invited us to leave. They claimed total jurisdiction because it was a hijacking case. Lt Bernie Kiessling looked at the Senior Agent and said FU I have a dead cop lying on the floor, a dead copilot and a wounded pilot. He said murder was a state crime and invited them to leave. Finally we agreed to work together. The Secret Service took custody of Buck’s tape recorder and refused to share it because of the assasination attempt and national security issues. Wish I could have gotten a copy.
