In fairness to you, Mr. Smith, you do raise two important questions:
1. Why can't Mr. Smith explain why the number 270 was chosen to start marking the Ruth Paine Exhibits?
2. Why can't Mr. Smith explain away that 27.5 is the EXACT SAME as the length of the curtain rods?
Oh, how the lowly have fallen!
Unreal. Let's go over this very slowly.
1) The handwritten notation indicates that the curtain rods are "marked" 275 and 276. Again "marked."
2) The term "marked" in the context of an item of evidence is a number used for identification purposes. It has absolutely nothing to do with the length of the object.
3) The WC exhibit numbers for two curtain rods taken from Paine's garage are also 275 and 276.
4) There are no decimals in the notation to 275 or 276.
5) The numbers 275 and 276 are not followed by any unit of length (e.g. inches, centimeters, feet etc)
6) Why would two curtain rods taken for the same source have different lengths?
Lastly, there is an enormous logic fallacy to this conspiracy fantasy. It would have us believe that four months after successfully framing Oswald for the crime including debunking his story to Frazier that he carried curtain rods that morning (a story that Oswald himself denied he told Frazier) and instead had his rifle in the bag, that the authorities would on their own volition document and bring to light those very same curtain rods that they are tried so hard to suppress. To check for Oswald's prints! Wow. You should be ashamed.
