Who took the pic? Someone significantly taller than either of them. Why is Clinton wearing what looks like street shoes (no tread) to walk in the woods? The woman just happens to go for a walk in a coordinated outfit that matches her baby backpack, and has on makeup...for a walk in the woods. Who is the dog looking at, the SS agents? Why 720x960, that is a typical video resolution, not a common one for a spontaneous cell phone shot. This is probably a frame grab from a professional videographer using a DVC camcorder.
This is so obviously a setup it is insulting that they'd try to pass it off as some spontaneous "look I'm alright" thing.
