There is no pool of blood or other signs of a body being crushed. Looks like a person crawled under the vehicle while it was sitting still and they threw some animal guts in front of the wheels. Look at the picture from the front and you can see that the person is not flattened.
Also, if this is such a top secret event, why did they allow someone to take pictures not only from the side but the front as well? Where is the government personnel who carried this out? Why did the vehicle stop instead of continuing on?
Too many things do not add up in these photos.
If you look at the photographs, it would seem to indicate that the feet should have been crushed as well.
