Everyone knows that the assassination rifle was found on the 6th floor of the TSBD with a telescopic sight mounted on it, and it is assumed that Oswald used this telescopic sight for at least one of the shots. What is not commonly known is the type and quality of this scope, the type and quality of the scope mount, the quality of the work in mounting the scope to the rifle and how all of these factors would affect the sighting in of this telescopic sight plus the ability of this telescopic sight to remain sighted in any longer than the next successive shot.
Using testimonial evidence presented to the Warren Commission, I will show why Oswald, who had rifle training in the USMC but who was never trained in the use and maintenance of a telescopic rifle sight, would have quickly become frustrated with the gross deficiencies of the telescopic sight on C2766, and would have removed the telescopic sight and mount from this rifle long before 22/11/63.
The rifle with the scope mounted could be aimed with the scope or the iron sights. The scope in no way prevented the iron sights from being used. This has been demonstrated in firing tests with that type of rifle. This is just one of those inconvenient truth that many wish to ignore.
While using the scope was not a realistic option for aiming the scope (probably not, but we will never know for certain) there are many reasons why Oswald would chose to keep the scope mounted.
1. It did not prevent the iron sights from being used.
2. It makes the rifle look more “lethal”. Like the assassin really knew what he was doing when he used it as the murder weapon, because it had a scope.
3. If nothing else, the scope could help him identify JFK as soon as possible, after rounding the corner onto Houston Street, allowing him to know as soon as possible which vehicle JFK was in and where he was sitting in. He could see this without having to take the time to put down his rifle and pick it up again.
4. Oswald was known to want to leave behind images that show how dangerous he was, which could increase his notoriety, after he, hopefully, escaped over the border
a. The pictures he had his wife taken of him with his rifle, with the scope clearly visible and his handgun.
b. The Same pictures that show him dressed in black.
c. His insistence, just before leaving the jail, to dress in black, to wait for his black sweater to be brought to him, which ironically delayed him just enough to allow Jack Ruby to arrive just in time to shoot him.
At best, one can argue that the scope would be perhaps an annoyance that he might have want to ignore. But many people pretend that this arguments don’t exist and it really only makes sense for him to remove the scope before using the rifle.
