It doesn't take Sherlock Holmes to puzzle this out. Oswald carried a long bag that morning that contained some incriminatory item (the reason he later had to lie about it). That item was the rifle. The bag he used was long enough because it was found and measured. As a result, there is no reason to speculate or rely upon an estimate of its size. We know how long it was because it was found and measured.
It doesn't take Sherlock Holmes to puzzle this out.Now what? Do we mean it doesn't take Sherlock Holmes to solve this? We know the paper bag existed because it did.
Brilliant Watson!
Deep in the archives exists two entirely different statements concerning the paper bag and it's analysis.
The reports are identical in every way except one--where the FBI found that the paper had the same characteristics as the kind used at the TSBD...and one where the paper did NOT have the same characteristics.
Sherlock...where are you?
