Then who dropped it and how do you know who dropped it? You used the wrong fallacy, this is not even close to a Straw Man argument...
(b) The weapon wasn't exactly well-hidden. Oswald (or whomever) could have put it in an outgoing box destined for shipment to himself and it would never have been found in the Depository, correct? Instead it was found on the northwest side of the building immediately next to the stairwell that leads to an escape. Oswald (or whomever used it, but most likely Oswald) would have carried the weapon to the stairwell to facilitate his escape (he didn't know how quickly the cops would respond, and indeed, one of them [Officer Baker] was inside the building within about 40-60 seconds of the assassination). Once he reached the stairwell, the rifle (which could have been used to shoot one officer) was abandoned amongst some boxes. Having served its purpose, there was no need to take care of it any longer. The shooter would have simply dropped it amongst some boxes with one and shoved another box over it with the other. He would not have taken care to place it gingerly anywhere -- the goal at that point (whether the shooter is Oswald or someone else intent on framing Oswald) is to get out of the building as quickly as possible. Every second of delay adds to his chance of discovery. So I don't need to show proof the rifle was dropped. You would need to show evidence it wasn't, contrary to all the reasonable reconstructions of the event.
Wow, this is entertaining but nothing factual.
(c) The weapon had an out of alignment telescopic sight. That is consistent with it being dropped. It is inconsistent with it being handled carefully.
A weapon with an out of alignment telescopic sight being consistent with it being dropped is like frontal lobotomy being consistent with a headache. Both are correct but are not necessarily linked unless you can provide that one caused the other. All you have done is provided a guess.
The reasonable conclusion is the weapon was dropped - mostly likely when it was hidden. Ball in your court.

The ball has to be moved with facts and not with speculation, you have not provided anything that pushes your claim. Do you wish to include something that has merit? Heck, we are talking about a rifle that was never even tested for recent firings when in the hands of the Dallas Police or FBI.
