There were so many VERY odd things about this assasination, and it's aftermath. So many things just "do not compute".
I have read just about everything written about it several times, seen the Zapruder film and a couple of others (up to about 12 years ago when I lost interest), I always have to be skeptical of the Oswald "Lone Gunman" theory because of one practical, non-political thing.
The sticking point for me has always been the rifle that Oswald supposedly used. No serious shooter would select a surplus Carcano to do it. While the 6.5mm Carcano cartridge is moderately accurate at moderate range, the rifle itself is a piece of junk... I wouldn't even use one use one for "plinking".
Even if Oswald acted completely on his own, had no money for a good, accurized firearm and had to just buy a cheap one by mail order, he could have gotten a Mauser, a Springfield or several other GOOD, accurate weapons for about the same price or even less, and easier to find ammunition for them.
The Carcano just isn't a choice for a serious shooter, and I can't imagine anything more serious than shooting the Predident of the USA.
Nope, I'm going to continue to wear my tinfoil cap on this conspiracy ... Too bad I'm not likely to be around when they do actually unseal the real records.
And _Mike_ , I don't know about the Marine Corps... Their standards are probably higher, but in my day, in the Army, you got a Marksman medal for knowing which end the bullet came out of.
