The report stressed that "no conclusion is made as to guilt. The only conclusion made is that there is credible evidence meriting further investigation, by a proper authority, as to whether the threshold of criminal responsibility has been met."

Callamard said for instance that she had found evidence that "Khashoggi was himself fully aware of the powers held by the Crown Prince, and fearful of him.
