It must be causing you a great deal of anguish to have your silly little conspiracy theory get stepped on just because a couple of detectives were assigned to watch over the area. Are you coming to the end of these ridiculous odd theories that are basically meaningless to start with or are there more of them?
Maybe next time, read a little more before you start posting. There are numerous older threads that have dealt with this same information. You aren’t the first, just the latest.
So, the only problem you are having is where did Givens eat his lunch. Not did he or other workers eat a piece of chicken during the day? Wow, and now you are lying on the floor throwing a temper tantrum because Shelley noticed they would do just that?
Mr. Shelley’s, Det Johnson’s, and Det. Montgomery’s testimonies have not changed. If you look back on page 8, you can reread them. Maybe this time you will understand them.

Full meltdown mode, as expected.
For the THIRD time:
Do you agree that a partially eaten piece of chicken was found on top of the Sniper's Nest?
Now...here's the big one - Do you agree that a small lunch sack was also found on top of the Sniper's Nest?Have a closer read of Shelley's testimony, Jack.
He is, basically, asked if he saw anyone eating chicken on the 6th floor on the day of the assassination. It's a Yes or No answer.
His reply could not be more vague - he might have, perhaps, maybe said that to unnamed someone at some unspecified time. But it turns out Givens, the man that Shelley thinks perhaps might have been eating fried chicken WASN'T eating fried chicken at all and that it was further west in the building than where the lunch remains in the third aisle were discovered.
So it couldn't have been Given's lunch remains found ON TOP of the Sniper's Nest
even if they were Givens' lunch remains.According to Shelley, Givens had his lunch at 9:30 IN THE MORNING, which is utter nonsense.
Givens had his lunch at lunch time and he was stood outside the building when he had it:
Mr. BELIN. I want to backtrack a minute before we come to the shots. When did you eat lunch?
Mr. GIVENS. When did I eat lunch? I ate lunch after. Let’s see, no; I ate lunch before I went up there, because I stood outside and ate my sandwich standing out there.
Mr. BELIN. You ate your lunch outside?
Mr. GIVENS. Yes, sir. Standing in front of the building.
Mr. BELIN. In front of what building?
Mr. GIVENS. Texas School Book.
Mr. BELIN. Did you ever eat any lunch inside the building?
Mr. GIVENS. Yes, sir ; I eat inside the building all the time.
Mr. BELIN. On November 22, did you eat inside the building?
Mr. GIVENS. No, sir.There is no uncertainty in Given's mind.
He left his lunch in the domino room when he arrived at work and had his lunch at lunch time, stood outside the building.
Your little "two lunches" theory lies in tatters (like most every other theory you propose).
But, just for laughs, kindly explain to the forum how Given's imaginary lunch remains made it all the way over to ON TOP of the Sniper's Nest and where did they disappear to by the time Studebaker arrived on the scene.
