As usual, CTers focus on the misaligned scope. We don't know if the scope was misaligned. However, I think it almost certainly was misaligned.
But this ignores the alternative. What about using the iron sights?
* The iron sights could have been used instead of the scope. The scope did not "block the view" or prevent the use of the iron sights.
You obviously don't know much about military sharpshooters. A sharpshooter must practice regularly and Oswald would have practiced for such an important job. Did he ignore the scope and use the iron sights during practice? Of course not, Oswald would have sighted-in the scope during practice.
*Oswald was trained in the Marines to use a rifle with iron sights. He never received any training using a scope. He was able to hit a human size targets at ranges of 200, 300 and 500 yards, using iron sights.
Then why did Oswald leave the scope on the rifle if he wasn't going to use it? Don't claim that the scope would not have obstructed his view via the iron sights. How many sharpshooters would do this? None.
* While Marines are only trained with stationary targets (it appears to be impracticable to train thousands of recruits at once using moving targets) they have proven time and time again to be proficient at hitting moving targets in battle.
* The Marines at Guadalcanal used the M1903 Springfield rifle, with iron sights, with great effectiveness, even against moving targets, Japanese infantry charging at greater speeds than the limousine at Dealey Plaza.
Non sequitur/false equivalence
Conclusions:
* A sharpshooter would not have used a misaligned scope.
* A sharpshooter would not have kept the scope on the rifle if they did not intend to use it.
* A sharpshooter would have practiced with the rifle beforehand and sighted-in the scope.
* Oswald would have removed the scope from the rifle when he disassembled it and placed it into a paper bag if he did not intend to use it.
* Oswald did not even touch the rifle since there were no prints on it or gunshot residue on his face.
* Oswald could not have taken any shots because there wasn't a valid trajectory from the 6th floor of the TSBD into JFK's back and out his throat.
* The MC did not shoot magic bullets.
