During the evening of November 22, the Dallas Police Department performed paraffin tests on Oswald’s hands and right cheek in an apparent effort to determine, by means of a scientific test, whether Oswald had recently fired a weapon. The results were positive for the hands and negative for the right cheek.[C4-669] Expert testimony before the Commission was to the effect that the paraffin test was unreliable[C4-670] in determining whether or not a person has fired a rifle or revolver.[C4-671] The Commission has, therefore, placed no reliance on the paraffin tests administered by the Dallas police. (See app. X, pp. 561-562.) Oswald provided little information during his questioning. Frequently, however, he was confronted with evidence which he could not explain, and he resorted to statements which are known to be lies.[C4-672] While Oswald’s untrue statements during interrogation were not considered items of positive proof by the Commission, they had probative value in deciding the weight to be given to his denials that he assassinated President Kennedy and killed Patrolman Tippit. Since independent evidence revealed that Oswald repeatedly and blatantly lied to the police, the Commission gave little weight to his denials of guilt. Denial of Rifle Ownership From the outset, Oswald denied owning a rifle. On November 23, Fritz confronted Oswald with the evidence that he had purchased a rifle under the fictitious name of “Hidell.” Oswald said that this was not true. Oswald denied that he had a rifle wrapped up in a blanket in the Paine garage. Oswald also denied owning a rifle and said that since leaving the Marine Corps he had fired only a small bore .22 rifle.[C4-673] On the afternoon of November 23, Officers H. M. Moore, R. S. Stovall, and G. F. Rose obtained a search warrant and examined Oswald’s effects in the Paine garage. They discovered two photographs, each showing Oswald with a rifle and a pistol.[C4-674] These photographs were shown to Oswald on the evening of November 23 and again on the morning of the 24th. According to Fritz, Oswald sneered, saying that they were fake photographs, that he had been photographed a number of times the day before by the police, that they had superimposed upon the photographs a rifle and a revolver.[C4-675] He told Fritz a number of times that the smaller photograph was either made from the larger, or the larger photograph was made from the smaller and that at the proper time he would show that the pictures were fakes. Fritz told him that the two small photographs were found in the Paine garage. At that point, Oswald refused to answer any further questions.[C4-676] As previously indicated, Marina Oswald testified that she took the two pictures with her husband’s Imperial Reflex camera when they lived on Neely Street. Her testimony was fully supported by a photography expert who testified that in his opinion the pictures were not composites.[C4-677] The Revolver
