To say that the photo was staged, is saying it is fake, and such scenes are not real.

it is too horrible to comprehend so i can 

understand why some people prefer to believe

the situation was not real, at the same time it is 

very unfair to accuse carter of staging it.  

and yes, he was deeply affected by what he saw,

not just that day.

Spoiler

Excerpts from Cater's suicide note read: "I'm really, really sorry. The pain of life overrides the joy to the point that joy does not exist...depressed ... without phone ... money for rent ... money for child support ... money for debts ... money! ... I am haunted by the vivid memories of killings & corpses & anger & pain ... of starving or wounded children, of trigger-happy madmen, often police, of killer executioners... I have gone to join Ken if I am that lucky."
