The shot tha Oswald took at about 60 yards is an extremely shot to make. I could have that as can many of my shooting buddies. Quite an easy shot.
60-70 yards with a scoped rifle and a slow moving car (SS agents were walking alongside.) is indeed very make-able.
I would compare it to an NBA player hitting 3 consecutive Free Throws.
Again, very easy and about 80% probability of success, if not higher.
I have always felt that Oswald was trying to shoot him in the dead center and that he missed his point of aim. If his scope, like most scopes, was set for 100 yards he would have aimed below the point of impact and over compensated for the difference between 100 yards and 60 yards.
So I think he didn’t impact where he wanted to.
