No. The implications of the bag being planted necessitate an implausible alternative chain of events regardless of "who" was responsible. And it is difficult to understand how anyone other than the DPD could have been responsible for planting the bag since they are the ones who controlled the crime scene, claimed to have seen it next to the SN, recovered it, and found Oswald's prints on it. Are you saying someone else could have done all that? The bag is photographed coming out of the building shortly after 2PM. So who else had access and control of the evidence within the TSBD to do all that before the bag emerges at that time?
Who is claiming the bag was planted?
I think we can agree the crime scene was less than securely controlled.
We have a number of police officers documented to have found it.....surely it can only be one. I believe Montgomery gets that nod.
They did not find Oswald's prints on the bag. That was the FBI on the 23rd.
The bag came out at 3pm.
Can you give us an idea when (approximately) it was discovered?
