However, if you look closely at the photo you provided, under the white object on the roof, possibly the sunroof or some type a light bar, you can clearly see her clothing underneath it, and it would appear her upper abdomen area was exposed.
We don't know what the white thing is or what it was made of. There is a speaker on top of the car. Maybe the white bar is like a lecturn or hand hold for use in a campaign. It is just possible that there was an upper abdomen shot, but I doubt it.
What difference does it make if she was shot? If the government wanted to make up a story, why make one certain to cause controversy?
