He wasn't a Russian linguist. He was an air traffic controller. In those days, one could get bonus points toward promotion by demonstrating knowledge of any foreign language.
What you need to focus on are two essential aspects: First, eliminate all the hype about assassination and politics and look at the crime as a straight murder. Who would gain what from JFK's death? Who had motive and who had opportunity?
This is only useful if one presupposes that the assassin is a rational actor, pursuing a rational goal.
Lee Harvey Oswald did not fit this description.
1. His head snapped BACK when he as hit with the third bullet. It is not possible for a relaxed person's head to snap forward when they're hit from the front. Don't believe me? Have someone smack you hard on the forehead when you don't expect it - which way does your head go?
Does that blow to the front of your head destroy large portions of your brain? All bets are off at that point.
2. Bullets are known to cause larger exit wounds than entrance wounds. And the higher the caliber, the larger the exit wound. If the bullet was a hollow point, it, too, would cause a larger exit wound.
Hydrostatic shock is known to cause very messy effects that do not follow the classic entry/exit wound paradigm. Hydrostatic shock comes into play with high-power ammunition and hitting a rigid body feature (such as the skull).
3. LHO was already behind and above JFK when he began to fire. The road in front of Dealey Plaza slopes downward at a fairly steep angle, so, IMO, it is possible that the first bullet could have traveled from about the middle of JFK's back and exit through his neck. In addition, LHO is known to have missed and one bullet ricocheted off the pavement. What if the bullet that ricochted was the one that hit him in the back (That's MY theory; it doesn't jive with other theories, btw)?
Congratulations, you have just made your own "magic bullet" theory. A wound from a ricochet looks very different from a direct impact--the ricocheting bullet will make an oblong entry wound, not a circular one.
4. To believe that LHO was the lone assassin, you also have to buy into the "magic bullet" theory - a theory so fantastic as to defy the laws of physics and perform impossible feats.
Every critique of the magic bullet theory relies on one hypothesis contrary to fact--the idea that Connaly was sitting at the same level as JFK and directly in front of him.
In actuality, Connaly was sitting on a jumpseat that was lower than the President's seat, and somewhat to the left. When you move Connaly's seat into the proper position, the path of the "magic bullet" becomes straight.
Last but not least, if LHO was the lone assassination, ask yourself this: What influence did he have on the President of the United States to get him to seal ALL of the documents for 70-plus years after the fact to make sure that everyone associated with the assassination and the government were dead before they were unsealed?
The government does this routinely to allow candor in deliberations. I've been part of acquisition review boards that are similarly sealed.
And did LBJ have to gain by doing so? Especially after Jack Ruby was dispatched to kill LHO?
Had Lee Harvey Oswald not gone back for a sweater, Jack Ruby would have gotten to the jail after Oswald was gone. So I guess Oswald was a co-conspirator in his own murder.
Who benefitted from sealing all of the documents if LHO really was the lone assassination?
I would first assume the JFK assassination industry. They're the only people who made one thin dime off of his death.
Believe as you like, it's a free country. Perhaps you'll be around when the documents are finally unsealed and will get to know the truth. I certainly won't live that long.
The long and the short of it is that we can debate the assassination until the cows come home and not agree on a single point - it doesn't prove either of us right.
I will take issue with some of your points about sealing the records. Participating in acquisition review boards is substantially different from participating in what was supposed to be an objective murder investigation. There was no reason to seal the documentation, unless . . . . .
JFK wasn't hit by hydrostatic shock, he was struck by a bullet.
You may have a point about my own "magic Bullet" theory, I don't claim to be an arms expert. Nonetheless, I don't subscribe to the notion that a ricochet wound necessarily has to be oblong.
I also disagree with your contention about the Magic Bullet theory. Every critique does NOT assume that Connally was at the same level as JFK. The facts still remain that the bullet believed to be the Magic Bullet entered JFK around the midle of his back and exited through his neck - suggesting an upward direction of travel unless JFK was leaning forward when the bullet struck. If we assume that he was leaning forward, the Magic Bullet theory still doesn't work given the fact that Connally was on a jumpseat at a level lower than the president. The bullet, while tumbling in mid-air after exiting JFK's body, would still have had to execute s turn in the neighborhood of 90 degrees give or take in order to assume a downward direction and strike Connally in the shoulder, exit his shoulder and strike his wrist then going through his thigh. Since it was shown that the Magic Bullet did NOT strike any of Connally's bones, the trajectory of the bullet still makes no sense. Since JFK had severe back problems and would not likely have leaned far enough forward for the Magic Bullet to have made all of those turns (and I don't believe that his back brace would have allowed him to), your own observation that Connally was seated forward of and below the president only adds weight to the ridiculousness of the Magic Bullet Theory. In short, the angles simply don't work out.
