Since you seem to want to ignore facts, let me simply repost my comment on this subject. Evidently you couldn't be bothered to read the post the first time I posted the link:

Ladmo:
To say it was only LHO is to reject subsequent findings that drew from a greater pool of information. The House Select Committee on Assassinations came to the conclusion that LHO fired 3 shots and that the 3rd shot killed him. The HSCA did eliminate many suspected groups like: the Soviets, the Cubans, the CIA, the FBI, the Secret Service, et al. most Lone Gunman theorists believe all of the above but depart when the committee said that a fourth (4th) shot was fired. Read the report and then come back and explain why they did not get that element correct.
I don't need to go back and read the report, because if you go far back enough in this thread I explained how the multiple shots/multiple shooters scenario occurred, and the science involved.
For your enlightenment, I'll do so again, and address the "open mic" evidence that even under ideal conditions would be suspect.
When a projectile is fired, and the velocity of the projectile surpasses supersonic velocity (approx. 1100 feet per second, depending on atmospheric conditions) the projectile creates a following sound wave in it's wake. Here's an animation with aircraft as the example:
Video link removed
As the projectile moves through the air, at every single terrain feature it passes, organic or otherwise, it creates (for lack of a better term) a mini sonic boom that is clearly audible if A) the projectile passes along past your location in the bullet path B) you're downrange being shot at and the round is a clean miss C) you're the shooter, firing a well suppressed firearm.
This phenomenon was first noted on record by Hiram Maxim, the inventor of what he called a Silencer, when he fired a 1903 Springfield rifle in the standard Gov. 30/06 caliber with his invention - Maxim fired down a country road lined with telegraph poles, and his observation was that it sounded like a "battalion of machine guns" as the bullet passed each pole, the sonic boom was clearly audible to him.
How does this relate to Dealy? as LHO fired, different observers at different points along the bullet's path heard these MSB's, mistook the MSB's for muzzle blasts or misinterpreted them as being shooter locations, and from those observers came their eye (or ear, if you want to be accurate) witness accounts of more shots than the three established and documented rounds, different directions of fire, etc. and the rest is CT grist for the mill
What goes right along with the reality of this phenomenon is the inability of an open mic to do anything other than record ambient sounds. A mic at different points in a bullet trajectory could easily record multiple "shots" from one single round fired.
At this point, I need to make an argument from my personal experience.
During the course of my professional life I've been around, and have a bunch of personal experience with firearms all across the board, I'm a qualified expert witness, instructor, armorer, etc. I did six years in the Army and 15 years in the PD, I've worked overseas, and in the ABC examples I noted above I'm three for three.
Every so-called "impossibility" wrt the actual firearm, ballistics and the mechanics of marksmanship noted by the JFK assassination CT hawkers is flat out ********.
The shooting was nothing special, the 6.5 x 52 is a good if not great cartridge, the projectile has a very high sectional density (better penetration) compared to other common .30 caliber class service rifle rounds and one of the stupid mistakes JFK CT hawkers made early on is that many of them didn't account for the simple fact that LHO's first round was chambered before he mounted the piece for a cheek weld - early explanations tried to assert that LHO had to mount, aim and then chamber the first round...stupidity that only a non trained individual would even consider.*
Go back to the other thread and read my post on the first page - like I said, I had an unusual childhood and was raised to believe one of the standard CT's, but my life out in the world living in the reality of the piece of this story I'm most familiar with taught me that the various CT's out in the wild are based on misunderstanding at best, flat out ******** and opportunism at worst, and belief in those CT's are based more in ignorance than knowledge.
*Note. There is one JFK "researcher" and CT hawker that has an actual background as a trained professional.
Unfortunately, this individual wasn't satisfied with his own version of events, or maybe his book editor wanted some more horsepower in the story, so this individual claimed that when he attended LE marksman training run in conjunction with one of the greatest combat and competition marksman that ever lived, this individual claimed that the great man told him that the Marine scout/sniper school at Quantico had run a test to duplicate LHO's shooting, but nobody could duplicate the feat, including the great man.
The only problem?
No such test has ever taken place at the school - the military is very funny, they keep records of everything, and no such records exist.
For my part, I went through the same LE school run by the great man, and although he taught much, LHO, JFK and assassinations never came up, and no other individual involved with TGM or the school had ever heard him make any such claim.
The book written by the hawker dropped into obscurity afaik, but I wanted to touch on it because non-professionally trained JFK hawkers have grabbed onto this particular ******** story as "proof."
The other fact germane to this story, the book was published after the death of the The Great Man - Carlos Hathcock, USMC, 1942 - 1999.
