Are you saying you know that Oswald's scope was misaligned during the shooting...?
Im going on the fact that the only way they could align the scope for elevation was to unsrew the mount itself and insert a shim and then rescrew the mount at a lsightly different angle.
IDK if you can physically damage a scope to only cause elevation mis alignment so bad that it requires adding a shim, but not cause any damage to horizontal alignment and do this in the 30 sec after the shooting, while also wiping prints off with a shirt or rag, and also while running with rifle acroos the floor at 10 ft per sec
