Rulli wrote her book in the 1980's - did you read it? If you read it, you would see the time and labor put into bringing facts to Natalie's death.
Natalie didn't fall. There is no logical explanation for her falling accidentally. Going out to tie up a dinghy is absurd. Rulli's book is not an exaggeration of facts or conspiracy oriented as are the Kennedy books. Suzanne Finstad says the same things Rulli says about what's on record the night Natalie died. If not for authors and good ones like Finstad and Rulli, no one would know the most important things needed to know about this travesty of justice.
You say there's no evidence Wagner killed Natalie, well there's plenty of evidence he let her die. There's also very little evidence to prove he didn't kill her. You've got a ventedda against an author. You do not think or present your idle thoughts logically but many people at this forum do speak logically. Instead of addressing the logic, you continue to condemn an author who did a great job in every aspect.
