Oswald's sack in the Sniper's nest.

[Jerry Freeman]

Back to the paper sack...
The idea that the bag was not properly photographed as it was supposedly found indicates impropriety right there.

The paper bag thread turns into bullet posts...A thread about the cab ride turns into paper bag post and the experts here are the most chaotic offenders of the bunch. Background----

Mr. STOMBAUGH. Yes, sir; I am. My mark is here on the blanket, and when this was received in the FBI laboratory this string was around a portion of it.
Mr. EISENBERG. Could you tell us what your mark is exactly, Mr. Stombaugh?
Mr. STOMBAUGH. Due to the fact this was a piece of fabric and hard to mark, I put a piece of evidence tape on the blanket, stapled it to the blanket, and put my initials "PMS" with the date 11-23-63 thereon.
Mr. EISENBERG. When did you receive this blanket, Mr. Stombaugh?
Mr. STOMBAUGH. This was approximately 7:30 a.m., on the morning of November 23, 1963.

This proves that  on the morning of the 23rd Nov 1963, the FBI was actively--- not engaged in pursuing all avenues of possibilities regarding the death of JFK--but with one goal...Lets pin it on Oswald.
Whose mark was on the blanket before Strombaugh 'received' it? What was the chain of evidence there?

I wonder if CE399 came from JFKs stretcher? That would radically alter the single bullet theory.

Off topic, but, yes, CE399 came from JFK's stretcher.

[Martin Weidmann]

Off topic, but, yes, CE399 came from JFK's stretcher.

Really? And you know this, how?

Even Tomlinson, who found the bullet, couldn't say which stretcher it came from.
And there isn't a shred of credible evidence that the bullet now in evidence as CE399 was ever at Parkland Hospital to begin with.

I went back to CE142 again and again and it was very interesting to me to find couple of images.
The circled case is believed to be Detective Robert Lee Studebaker case. Check the flash bulbs package.



I also found three Studebaker drawings and what is hard for me to understand is that he did not place paper sack, CE142 on any of those drawings. It was right in front of his eyes but, paper sack allegedly found inside the sniper nest, Studebaker was well aware of it but he did not place it on his drawings?

[Jerry Freeman]

J C Day said as much in his testimony---"To the best of my knowledge" basically means he was told what to say

No he didn’t say any such thing. And who taught you English vocabulary? I suggest you consult a dictionary.

I didn't catch that reply back then but certainly question the response.
Day stated --"to the best of my knowledge"... 8 times during his testimony.
I suggest that Mr Collins consult his testimony as meticulously as I before he starts sounding off
