The Chappaquiddick incident of 1969 has been called “the most discussed traffic accident in history” and “the most brilliant cover-up ever achieved in a nation where investigative procedures are well-developed and where the principles of equal justice prevail.” It is considered one of the great, unsolved mysteries of 20th century America.

There appear to be enthusiastic attempts to resurrect Edward Kennedy’s image. A new Kennedy museum at the Kennedy Compound in Hyannis Port has a special room dedicated to Ted, our Democratic Party lauds his legacy, and a new political thriller movie is in the works showing what Ted Kennedy “had to go through” in 1969. The theory these days, accepted by most, is that Kennedy was innocent of any serious wrong-doing. Either he was suffering from shock and should not be accountable for his actions, or Mary Jo drove off the bridge alone, or there was a real companion that Kennedy, Gargan and Markham were attempting to protect all these years through some sense of old-fashioned chivalry, to the detriment of their reputations and careers. The public indignation to the Chappaquiddick scandal, so passionate in 1969 and for a quarter century longer, seems to have all but disappeared.

Many friends implored Pinney not to write this book because of what it might do to the memory of a Great Man. “What’s the point?” they asked. “Think of all the good things he did. It was just an unfortunate mistake. No one cares about Chappaquiddick now. There won’t be any interest. You’re a Democrat, for God’s sake!” Before Bill put pen to paper he assured family and friends that if the science did not back up the new witness’s sighting, and what that sighting implied, he would abandon the effort. Bill had no wish to malign anyone’s reputation if the evidence did not back up the accusation. But the forensic science and medical evidence does back up the theory most strongly.

The Chappaquiddick incident is history, and these days attempts to ignore the historical record, or rewrite it, rarely succeed for long. Pinney was led, by the evidence, to accept that the underlying theory as set out in this book is true. As such, the truth has merit, and should be told.
