In response to Shawcross, Porter responded in the "NYRB" in July 1978: "As anyone who has seen the book will know, nothing could be further from the truth. We document the conditions under which the evacuation took place from Khmer refugee reports, as well as European and American eyewitness accounts." Porter further commented: "It is true, as Shawcross notes from my May 1977 Congressional testimony, that I have changed my view on a number of aspects of the Cambodian situation. I have no interest in defending everything the Khmer government does, and I believe that the policy of self-reliance has been carried so far that it has imposed unnecessary costs on the population of Cambodia. Shawcross, however, clearly does have an interest in rejecting our conclusions. It is time, I suggest, for him to examine it carefully, because it does not make for intellectual honesty." Shawcross responded caustically, "it is a tribute to his own integrity that he now agrees that the Khmer Rouge have imposed 'unnecessary costs' on the Cambodian people. He should, however, be a little more careful before he accuses others of deliberately falsifying evidence and of intellectual dishonesty."
