A few questions on the plans for LHO if he intended to kill JFK on 11/22/63. I assume these issues have been covered here before, but I'm only a sporadic visitor here...
1) Why would he order a rifle using an assumed name when he could have gone to almost any Dallas gun clinic without having to produce ID?
2) Why on earth would any assassin choose such an archaic and inaccurate WW II era weapon to kill the world's most powerful person?
3) What happened to the 7.65 Mauser found in the depository? Wouldn't that be the weapon a real assassin would opt for?
1) He risked being remembered by a gun clerk if he buys the rifle in person shortly before someone tries to shoot Walker in Dallas. If he had done so, CTers would be on here asking why he didn't just order a rifle by mail using an alias etc. Also, it's important to keep in mind that at the time he ordered his rifle, he was not contemplating a situation like the one on 11.22. He intended to use it to kill Walker but he would not leave it at the crime scene to be discovered. Using an alias provides some cover for his identity. And Oswald likely had no clue what, if any, records were retained by Klein's of his purchase. Murder entails risk. Oswald was willing to take that risk. Even if you don't accept any of those explanations and think it was stupid to order the rifle via mail, criminals often do dumb things that result in their arrest. What is being suggested by your question is that the evidence of Oswald's guilt is so overwhelming that we must conclude he is innocent.
2) There is no evidence that Oswald's rifle was incapable of the task. It was a lethal weapon. If Oswald had purchased a more expensive rifle, then CTers would be on here questioning where he got the money to purchase it etc. But if you are entertaining the outlandish possibility that Oswald was framed for the crime as evidence by the poor performance of the rifle, then why would your fantasy conspirators put such a rifle in his possession when they were free to connect him to any model that they wanted?
3) This question contains a false premise. No such rifle was found.
