Again, shouldn't we be comparing Oswald with the general populace here instead of with other Marines? He may have been at the bottom of the barrel in the Marines, but was he not arguably a better shot than the average Joe Schmoe walking the streets in Dallas, Texas, that day? And does the fact that he didn't measure up as a shot compared to other Marines make it metaphysically impossible for him to, starting out with one cartridge already chambered ... that is another fact that a lot of people overlook; people think he had to work the bolt three times during those few seconds, but it was really only two ... hit a completely open, slow-moving target three times (although he missed the first shot; that's another fact people don't consider when pooh-poohing the single bullet theory) at a range of between 170 and 265 feet with a rifle equipped with a 4X scope?
Oswald had not shot the rifle in months or years. There is not a shred of evidence that he purchased ANY ammo for it. And there is considerable doubt that he even picked up the gun at the Post Office box since he was at work at the time.
Then smartasses want to know why he would have bought this PoS gun mailorder leaving a document trail when he could have purchased cheaper and better rifles from hundreds of gun shops in Texas with NO trail. It makes sense if he was being set up to take a fall but none otherwise.
