If the backyard photographs are valid, they are highly incriminating of Oswald because they apparently link him with the murder weapon. If they are fakes, how they were produced poses far-reaching questions in the area of conspiracy. “Faked” backyard photographs would indicate a degree of conspiratorial sophistication that would almost necessarily raise the possibility that a highly organized group had conspired to kill the President and make Oswald a “patsy.”
