Every photo presented of the particular pose shows a sling to a lesser or greater extent, depending on the quality of each. Jerry has presented a high quality version.

My Dear Dumb ass... The point is:.... There is no sling on the rifle in the photo ( CE 133A) What appears as a "sling" in the photo is a ludicrous artist's idea of a sling that was added to the photo. The version of the photo that Jerry presented makes this FACT very obvious.
The point is.... FBI photo experts examined the photo... They most certainly knew that what appeared to be a sling was added to the photo and is definitely an alteration of the photo...
Have you ever seen any official acknowledgement that the photo has been altered?
