I agree! Something happened in March that caused a major problem for the Oswald-Acted-Alone investigation.
There is a third scenario:
Mr Oswald did not hide the curtain rods (they were not lethal weapons after all), he just left them somewhere-------and then found them gone right after the assassination. This would have been the moment he clocked how he had been tricked. The curtain rods were hidden by whoever framed him.
Probable side-issue!
Do we know for sure when this photograph was taken?
1. Some curtain rods were found in TSBD, early, during the searching of the TSBD, and someone decided to hide this fact, and kept this package until March 15th, when it became for some reason, a necessity to submit an official document of request for testing for fingerprints, to Lt.Day.
I disagree with this idea..... If there had been curtain rods found in or near the TSBD early in the "investigation"..... They would simply have destroyed them and swept the whole episode under the rug....
I believe it's more reasonable that someone like Frankie What's His Face who found the clipboard, found the curtain rods and they were compelled to go through the motion of checking them for lee's finger prints...... Of course it was a foregone conclusion that the curtain rods would have no connection to Lee Oswald....
