The Dallas Police found Oswald's Carcano rifle on the 6th floor of the TSBD 45 minutes after the assassination. Would the smell test have been of any use?
Why did it take 45 minutes to find it
The police sealed the building about 15 minutes after the assassination. The police proceeded to conduct a floor by floor search. I assume they went up to the 6th floor in the freight elevator. The rifle was hidden between some boxes near the entry to the 6th floor stairs.
Law enforcement found the rifle when they found it. Do you consider it suspicious that they did not find the rifle sooner?
