An analysis by the committee of the statements of witnesses in Dealey Plaza on November 22, 1963, moreover, showed that about 44 percent were not able to form an opinion about-the origin of the shots,(173) attesting to the ambiguity showed in the August 1978 experiment. Seventy percent of the witnesses in 1963 who had an opinion as to origin said it was either the book depository or the grassy knoll.21(174) Those witnesses who thought the shots originated from the grassy knoll represented 30 percent of those who chose between the knoll and the book depository and 21 percent of those who made a decision as to origin. Since most of the shots fired on November 22, 1963 (three out of four, the committee determined) came from the book depository, the fact that so many witnesses thought they heard shots from the knoll lent additional weight to a conclusion that a shot came from there.
