Two obnoxious things about the bridge scene
First off, their yelling at each other about who was going to kill the girl was ten times louder than the girl's coughing.
Second, no way they would be firing at the girl on the tracks like that. They were all in each other's line of fire, and they would have killed each other.
Finally, not obnoxious but just a question - would there really have been a railway left in Vietnam that hadn't been bombed to sh!t? That seemed implausible to me.
I want the doctor to take your picture so I can look at you from inside as well.
