Jean, not to hi-jack your thread, but I read through the list of negatives in Document 7 for which you had provided a link. In particular, pages 382-386 contain notations in parenthesis stating disclaimers by Lt. CARL DAY, DPD crime scene photographer. The aforementioned numbered negatives are #4, #5, #6, #12, #13, #34 & #40 (see images in this reply or click on link).
Two disclaimers are mentioned: RECONSTRUCTED crime scene & lunch bag with soft drink bottle on 6th floor was determined to NOT be Oswald's, but rather, another employees.
Perhaps someone can briefly explain these disclaimers by Lt. Day for me. The DPD didn't take photographs of the crime scene AS FOUND? I would see no reason to turn over negatives of RECONSTRUCTED crime scene photos to the FBI, let alone reconstructing them in the first place. Give them negatives of the crime scene AS FOUND.
Also, prior to this document, I don't recall ever seeing something to refute that the lunch bag and soft drink bottle were NOT Oswald's. The MSM has sure went out of their way to make it appear as though LHO was dining in his perch waiting for JFK.
I am not a researcher and have not studied all factions of this case vehemently. I genuinely ask because I am ignorant in regards to the reasons for RECONSTRUCTING crime scene photos (I would think RECONTRUCTED crime scene photos are inadmissible as evidence in a court of law) and has the ownership of the lunch bag and bottle been properly assessed. If it was another employee's lunch bag & bottle, who was it and when were they there? Seems like you would follow that up.
