I'm sorry if this is a re-post.
First pic: This man took a bad gunshot to the head. It blasted part of his skull off leaving him dead on the ground with brain and blood flowing down through the dirt. He probably died instantly, before he could suffocate from breathing in his own blood, as it would seem from the photo.
Second one: This Iraqi man, on the other hand, took a gunshot straight through his head. It didn’t blast half of his skull off, but went right into the brain. He definitely didn’t suffer too long. It looks like a well aimed gunshot, probably from a skilled sniper who hit it right where it counts. Instant severe brain damage = instant death. Both from Iraq, both took it in the head.
Photo one looks like a young teen.
