Another point worth mentioning is that Barry Krusch (M.A., B.S.) proves in Impossible: The Case Against Lee Harvey Oswald, Volume 3 that WC counsel David Belin realized that boxes were moved around in the sniper's nest between the time CE 482 was taken and the time CE 715 was taken, i.e., between 1 minute after the shooting and shortly after the arrival of Day and Studebaker to the sixth floor at 1:12. IOW, Belin reached the same conclusion as the HSCA photographic experts, i.e., that boxes were moved in the sniper's nest after the alleged lone gunman had left the sixth floor, but Belin did so on different evidence. Belin detected this by comparing CE 482 with CE 715, which should show the same configuration of boxes but clearly do not.
Belin questioned Deputy Sheriff Mooney closely about the conflict between CE 482 and CE 715. Mooney insisted he did not move a single box in the sniper's nest but stood guard around the nest until Day and Studebaker arrived. Belin may have suspected that Mooney moved the boxes but just didn't want to admit it. If Belin had considered the Powell and Murray photos, he would have realized the boxes were moved before Mooney got to the sixth floor.
