Regarding the deflected first shot, it comes from Posner's book, Case Closed.
The Warren Commission did determine that one man could fire all 3 shots, so I don't understand your last sentence.

I hope the following will explain to your satisfaction that the "lone gunman" theory could not be sustained by the rifle test conducted by the Warren Commision's own tests.
The Warren Commision employed three riflemen rated as Masters by the NRA to fire the Mannlicher Carcano during shooting tests. Out of 5 shooting NRA grades, Master is the highest level and only awarded to the most outstanding riflemen. Two of the riflemen where were civilians and one was in the US Army at the time of the tests. The 6th story window was 60 feet off the ground where the Master Marksmen fired from an elevation estimated by Ronald Simmons, Chief of the Infantry Weapons Evaluation Branch of the Ballistics Research Labratory of the Department of the Army, to be 30 feet off the ground. Oswald supposedly fired at moving target where the experts fired at a stationary targets. In the simulated environment these experts could commence firing whenever they were ready where the assassin(s) had to shoot while the target presented itself.
In addition to this circumstance the rifle sight was rebuilt. As Simmmons states, "they could not sight the weapon in," he explains "well they could not sight the weapon in using the telescope." Simmons also pointed out that rifle aiming device was rebuilt by a machinist who added two shims, one which tended to adjust the azmith and the other the elevation. Simmons, just like the riflemen, was employed by the Warren Commission.
The experts fired two series of three shots, 6 each for a total of 18 shots, at three stationary targets placed at distaces of 175, 240 and 265 feet respectively. According to Simmons who arranged the test the targets were not as far apart as they should have been to represent the actual position of the limo. Simmons stated that the condition of the field was a "little awkward."
Of the three experts, only one was able to get off the three shots in the required time where he fired three shots 4.6 and 5.1 seconds. The other two Master Riflemen required 6.45, 6.75, 7.0 and 8.25 seconds. Not one of the 18 shots struck the head or neck area of the targets. These tests where conducted under far less demanding circumstances then was attributed to a below average shooter LHO. So you not only have a rifle and rifleman unable to make these shots but you have 3 outstanding riflemen, not "novices," at far less demanding conditions with a rebuilt scope unable to score one hit on easier shots and only 1 to make the shots in the time frame as determined by the Warren Commission.
This major problem was addressed to some degree by Buglioso where he claims that Oswald used the iron sights. I am not sure what sight picture the Mannlicher Carcano would offer with a scope on the weapon but I addressed the unlikelyhood of that issue in earlier post. What is worth noting is that Bugliosi knows that the rifle and scope on the Manlicher Carcano make for a bad theory.
