CE 399, the single bullet described in the theory

The single-bullet theory, also known as the magic-bullet theory by conspiracy theorists,[1] was introduced by the Warren Commission in its investigation of the assassination of U.S. President John F. Kennedy to explain what happened to the bullet that struck Kennedy in the back and exited through his throat. Given the lack of damage to the presidential limousine consistent with it having been struck by a high-velocity bullet, and the fact that Texas Governor John Connally was wounded and was seated on a jumper seat 1+1⁄2 feet (0.5 meters) in front of and slightly to the left of the president, the Commission concluded they were likely struck by the same bullet.

Generally credited to Warren Commission staffer Arlen Specter[2] (later a United States Senator from Pennsylvania), this theory posits that a single bullet, known as "Warren Commission Exhibit 399" or "CE 399", caused all the wounds to the governor and the non-fatal wounds to the president, which totals up to seven entry/exit wounds in both men.[3]

The theory says that a three-centimeter-long (1.2") copper-jacketed lead-core rifle bullet from a Model 91/38 Carcano, fired from the sixth floor of the Texas School Book Depository, passed through President Kennedy's neck into Governor Connally's chest, went through his right wrist, and embedded itself in Connally's left thigh. If so, this bullet traversed a back brace, 15 layers of clothing, seven layers of skin, and approximately 15 inches (38 cm) of muscle tissue, and pulverized 4 inches (10 cm) of Connally's rib, and shattered his radius bone. The bullet was found on a gurney in the corridor at Parkland Memorial Hospital after the assassination. The Warren Commission found that this gurney was the one that had carried Governor Connally.[4]

In its final conclusion, the Warren Commission found "persuasive evidence from the experts" that a single bullet caused President Kennedy's throat wound, and all of the wounds found in Governor Connally.[5] It acknowledged that there was a "difference of opinion" among members of the Commission "as to this probability", but stated that the theory was not essential to its conclusions and that all members had no doubt that all shots were fired from the sixth-floor window of the Depository building.

Most critics believe that the single-bullet theory is essential to the Warren Commission's conclusion that Lee Harvey Oswald acted alone.[6] The reason for this is timing: if, as the Warren Commission found, President Kennedy was wounded some time between frames 210 and 225 of the Zapruder film,[7] and Governor Connally was wounded in the back/chest no later than frame 240,[8] there would not have been enough time between the wounding of the two men for Oswald to have fired two shots from his bolt-action rifle. FBI marksmen, who test-fired the rifle for the Warren Commission, concluded that the "minimum time for getting off two successive well-aimed shots on the rifle is approximately 2 and a quarter seconds", or 41 to 42 Zapruder frames.[9][10]

The United States House Select Committee on Assassinations published their report in 1979 stating that their "forensic pathology panel's conclusions were consistent with the so-called single bullet theory advanced by the Warren Commission".[11]

  2. ^ Warren Commission staff lawyer Norman Redlich was asked by author Vincent Bugliosi in 2005 whether Specter was the sole author of the single-bullet theory and he said "No, we all came to this conclusion simultaneously." When asked whom he meant by "we", he said "Arlen, myself, Howard Willens, David Belin, and Mel Eisenberg." Specter did not respond to Bugliosi's request for a clarification on the issue.
