This was such a great find by Amy Joyce, the grey stripe in the ribbon of "Ruby's" hat in the Jackson photo.
That was painted in because they didn't have Photoshop in those days. And, of course, it didn't occur on Ruby's hat, as you can see on the right. And that means that the Jackson photo was definitely altered by somebody. There is zero chance that that image came out of Jackson's camera as the original. So, there is NO CHANCE that the Jackson photo was in Jackson's camera until he got back to the newspaper and developed it. Unless you want to say that Jackson did it? But, he has never admitted any such thing, and there is no reason to think he would do such a thing. What for? The delay in his getting back to the paper was because authorities took his film. They had to look at it before he could have it.
