With the horrible Daniel Pearl story and another recent story about an injured journalist in the Middle East, I began wondering how these folks do their jobs? How do they get footage of actual battle? Do armies allow cameramen behind their lines to take pictures? Do they exert any control over the content of the coverage? Are there international agreements designed to protect journalists? Do these journalists arm themselves? If I were running an army, it's hard to imagine I would allow any extraneous people around that could possibly interfere with or compromise my operations.
