On November 24, 1963, nightclub owner Jack Ruby shot and killed Lee Harvey Oswald, the accused assassin of President John F. Kennedy, in the basement of Dallas police headquarters. The shooting was captured live on television as Oswald was being transferred from the city jail to the county facility. Ruby was immediately arrested and later convicted of murder, though his conviction was overturned on appeal before his own death. The killing prevented Oswald from standing trial and answering questions in court. The episode fueled widespread conspiracy theories about the Kennedy assassination. It also led to tighter security rules for handling high-profile prisoners.
