You think Jackie caught the bullet in her hand and placed it there? That is far out.
Well, unlike you I wasn't there so I can't be sure. But these frames offer the possibility that a bullet may have dropped down into her left hand and she placed it just where Mr. Landis says he found a bullet. The particular fashion in which she lays her hand down right over the 'seam' area is certainly suggestive of that
In a sense, the sheer oddness of the place where Mr. Landis says he found a bullet may speak to the veracity of his story. If you're going to make up a story of finding a bullet in the car, you wouldn't say the bullet was
there of all places. Seems so wildly unrealistic.
And yet here we have Zapruder showing us just how that improbable thing might easily have happened.
