I want to preface my comment by saying that I'm not against a multiple gunmen theory, or CIA + Cuba + Russia + LBJ + Illuminati + Cthulhu worshippers being behind the assassination of President Kennedy --- only that I believe that Oswald could certainly have been a trigger puller on that day.
As far as the 'Magic Bullet Theory' goes, I should note that one of the first eye-opening experiences I had with the crazy things high-velocity rifle bullets do was as a machinegunner in the Marine Corps. In that role, you tend to have a job where you shoot more rounds in a year's time that most other service members will do in their whole career. You get to see firsthand what the effects are on all sorts of various targets -- Armor plate, dirt embankments, tree trunks, tree limbs, bushes, tires, barrels, GI cans filled with water, unexploded ordnance on occasion, vehicle relics, trash and crap, etc. etc. etc.
The thing that really makes an impact is tracer rounds during night fire at the range. Some tracers jump up in the air and spin like a glowing ball, some zig-zag after bouncing off three small rocks, some make trails like a bolt of lightning, etc. I've even had some shots damn near come right back at me when shooting at a range that has a lot of fired lead buildup. They all describe the random bullet path of each round fired. They don't all do that, but you get to witness some weird shots numerous times per night.
When I really sat down to read the account of the 'Magic Bullet Theory', it later made me think several things:
1. Was the path of the 'Magic bullet' a lot straighter than the anti-'Magic Bullet Theory' conspiracists lead us to believe? They claim that Kennedy and the governor of Texas were at precisely this angle with their arms just so and their torsos angled exactly in such a way based solely upon the Zapruder Film. I look at the Zapruder Film and think that they've got a great imagination. I see a short and blurry home video starring Jackie Kennedy wearing a big ass hat right before JFK's head explodes.
2. Rifle bullets have a lot of punching power. Fold a piece of paper over on itself a few times and poke a pencil through it. Have you made one hole or multiple seperate holes?
3. I believe in the *possibility* that the Carcano bullet could have zipped around in a skewed path causing several wounds to Kennedy and Connally and come out partially intact. I only say this because I've personally witnessed bullets do strange things after they hit and picked up damned near pristine bullets fired downrange on numerous occasions.
Ever seen strange things happen on the break in a game of billiards? It's a lot the same way. I landed a cue ball inside someone's pitcher of beer five feet away from the table with a giant sploosh one time and the triangle of balls on the table hardly broke up.
In relation to the rest of the Kennedy Assassination conspiracy, I can't say that I'm a serious student of the Warren Report or a fanatic about the subject. I'm interested, but not scholarly about it. I just wanted to make the point that I noticed that just about all conspiracies about the assassination of President Kennedy are based upon the belief that Oswald couldn't have made the shot because bullet will always take on a ballistic laboratory's flight characteristic expectancies.
It just ain't always so. Why not this time?
As for LBJ being in on the murder, or the CIA, or the Soviets, or Castro... Who knows? That's not my point.
