I think that the index finger may have been "edited" into the picture. If you look at at, it appears to be at an unnatural angle, and the size is out of proportion to the hand.
Another individual in this picture that I find interesting is the man with his back to the camera, with the tan shirt on sitting next to the pole... is he sleeping? I know that I would be.
Why aren't any of the children dressed up in their pretty little suits and ties? I had to wear one of those damn ties when I was a small child, they get to wear sweat-shirts and jeans.
