All of this speculation about Oswald's rifle capability is a red herring. All of the evidence found indicated that it was Oswald alone who shot and killed JFK. Regardless of how he scored in the firing test while in the USMC, how many times Oswald worked the bolt to familiarize himself with the weapon, how many times he managed to practice with the rifle while in New Orleans, whether you believe Marina, the accuracy of the MC with and without using the scope (nobody knows if Oswald actually used the scope), the actual timeline of the sequence of shots if the first shot missed could be as long as over 8 seconds, the evidence strongly supports the fact that it was Oswald who was the SN shooter. NO OTHER SUSPECT HAS BEEN FOUND WHO COULD HAVE BEEN THE SHOOTER! Oswald pulled the trigger three times, missed the first shot, scored a hit on JFK that went through his neck, out his throat, entered JBC as the 6.5 mm WC copper jacketed bullet was beginning to yaw at approx. Z224, went out JBC's chest, struck his right wrist, and made a small puncture wound in his left thigh. That bullet, CE-399, was recovered at Parkland Hospital and accounts for two (the other being CE-567 and CE-569) of the three bullets fired. It's that freaking fu****g simple, yet you dumb a** commie loving, wife beating, turncoat Oswald defenders just refuse to face the facts just as the dumb a** Flat Earth believers refuse to believe in what is the most obvious of facts.
In order to support the myriad of theories to cast doubt on Oswald's guilt you fail each and every time in providing an alternate theory backed by reasonable evidence to support the theory that Oswald was not the shooter. Every time some half a***d unreasonable point is brought out by you guys it's countered by reasonable, effective, and verifiable evidence that completely shuts the door to further inquiry but you still persist because your life revolves around trying proving the unprovable by inventing unsupportable scenarios. It's your life and you can live it as you choose but you will never be at peace with yourselves because you're emotionally glued to a lost cause.
