Asked to account for these differences at the trial, the prosecution produced a second report, allegedly lodged 75 minutes after the murders which recorded the two rounds. They were unable to explain why, having that evidence, the police released the men, or why standard 'bag and tag' procedure was not followed. They also argued since the expended rounds retrieved at the scene were also a mixture, the fact the two rounds did not match was meaningless; what did matter was they were the same caliber as those used in the shootings.
