All that was needed was a motivated Marine and his rifle making an easy shot into a convertible.
You don't need an elaborate conspiracy for that involving Bush, Halper, aliens, reptilians, Colonel Sanders, the Rothchilds...
Occam's Razor. Learn it. Love it. Live it.
You got some of the key words, “motivation” which came from ‘influences’ which I mentioned before.
The part you are missing is knowledge and preparation. The President’s motorcade route and timing was unknown. Again, these are “reasonable’ suspicions that any detective would consider.
Until recently, it was not known that Oswald was tied to the CIA. That opens the door to reasonable questions of other CIA related connections.
You are correct Sir! From William Manchester, former Marine, page 95, in his book The Death of a President:
“A subsequent controversy developed over whether or not the shots fired from the warehouse on November 22 had been difficult ones, and echoes of the dispute are heard today. Here the author must appear briefly as an exert witness. This writer has carefully examined the site in Dallas and once qualified as an Expert Rifleman on the U.S. Marine Corps range at Paris Island, S.C. firing the M-1 rifle, as Oswald did, from 500, 300, and 200 yards. From the sixth floor in the Book Depository Oswald would look down on a slowly drifting target less than ninety yards away, and his scope brought it within twenty-two yards. At that distance, with his training, he could scarcely have missed.”
And don’t believe any of that crap about the 6.5×52mm Carcano Model 91/38 infantry rifle being a lousy weapon. 11 volunteer marksmen, who (unlike Oswald) had no prior experience with a properly sighted Carcano, were able to hit the test target twice in under the time allowed, although they were all afforded multiple attempts. The only man who scored three hits was firearms examiner Howard Donahue from Maryland.
The FBI tests of the Carcano’s accuracy showed:
1) FBI firearms expert Robert A. Frazier testified that “It is a very accurate weapon. The targets we fired show that.”[63] From 15 yards (14 m), all three bullets in a test firing landed approximately 2½ inches high, and 1-inch (25 mm) to the right, in the area about the size of a dime (0.705 inch diameter).[64] At 100 yards (91 m), the test shots landed 2½ to 5 inches (130 mm) high, within a 3 to 5-inch (130 mm) circle. Frazier testified that the scope’s high variation would actually work in the shooter’s favor: with a target moving away from the shooter, no lead correction would have been necessary to follow the target. “At that range, at that distance, 175 feet (53 m) to 265 feet (81 m),[65] with this rifle and that telescopic sight, I would not have allowed any lead — I would not have made any correction for lead merely to hit a target of that size.”
2) The rifle couldn’t be perfectly sighted using the scope (i.e., thereby eliminating the above overshoot completely) without installing two metal shims (small metal plates), which were not present when the rifle arrived for testing, and were never found.[66] Frazier testified that there was “a rather severe scrape” on the scope tube, and that the sight could have been bent or damaged. He was unable to determine when the defect occurred before the FBI received the rifle and scope on November 27, 1963.
I agree with you. I have been at the Sixth Floor Museum and looked down at Elm Street. My first reaction looking down is what an easy shot it would have been.
