from the interview with Garrison's people...
"Given Hargis' position to Kennedy's left and behind him, he should have been able to see the back of Kennedy's head blow out, if that indeed had happened. Yet he explicitly says that he saw a "splash come out on the other side." He, in other words, is describing a wound to the right side of Kennedy's head. So it's deeply ironic that conspiracy authors have used him as a "back of the head" witness. "
