And the weapon was not perfectly sighted.

Well you're both right. The error at 80 yards was about 2", up and to the right (good enough for the job)

The only question was did Oswald know about the error.

1. He did and tried to compensate - which for the shot taken would actaully mean no effort to compensate at all - LHO just aims where he wants the bullet to hit and allows the movement of the limo "forward and to the right" (Sorry Kevin Costner momemt) to carry the aim point to the bullet impact.

2. He did not know and tried to compensate. If he aimed at the base of the skull, compensated perfectly and made the best shot of his life, then bullet three would have hit Kennedy in the exact point of the actual final shot.

Either way it's a non-issue

I am surprised that even here on FreeRepublic where people are supposedly more rational and educated, that this argument is still going on. It has been shown over and over that Oswald could have done this. I guess people want to feel special by ‘knowing’ something secret that no one else does..

3. The sheetmetal scope mount was bent when Oswald threw it between the boxes on his way to the stairwell.

Look at the photo showing the officers pointing toward the rifle as it lays between the boxes. They had to climb over some of the boxes to point out where the rifle was. I don’t believe Oswald took the time to carefully hide the rifle there. I believe he threw it there. After all, he wasn’t coming back for it.

Either way you are correct. It’s a non-issue.

Yes, correct. In short, as you've essentially said, the misadjustment actually aided Oswald in the shooting.
