Thomas G. Buchanen and Joachim Joestin had books out in 1964. Weisberg's book wasn't out til '65. Weisberg's book was the first critical study based on a close analysis of the twenty-six Warren Commission volumes. It is the most strident, bitter, and generally irrationally biased of all the attacks on the Commission. Out of charity, we will mention it no further.
Whitewash is a carefully researched book, although somewhat shrill in tone.
Harold Weisberg is one of the most indefatigable critics of the Warren Report. Nothing the gander dislikes is good for the goose. Weisberg raised geese. Low-flying helicopters disturbed them, but it is unlikely that they, the helicopters, got up enough speed to break the sound barrier. Surpassing Weisberg in the capacity to be unloved was David Lifton, a pushy UCLA engineering student, who eventually wrote a book called Best Evidence .
