Same page as the above quote from “No More Silence” the paragraph just before that quote:
Before I got the picture made, another message came in: “Drop everything! Don’t do anything else!” It must have been 9:00 o’clock or later. “Drop everything! Don’t do anything else!” This came through my captain, Captain Doughty, but it probably came to him from Deputy Chief Lumpkin. So we didn’t complete what we were trying to do. I’d have probably been working on it all night if I’d had the time.
More morphing memories....
It still doesn't make any sense. What picture is he talking about? And even if he is told to "drop everything", how would that be enough to discontinue an examination of a print he allegedly found on the rifle. He was told to turn over all the evidence to the FBI, that same night, but according to his WC testimony he did not follow that instruction and held back the evidence card with the print.
Apart for anything else, as a forensic officer he must have understood the significance of a print found on the alleged murder weapon, yet he does nothing and keeps it in his desk drawer for days.... really?
