If he truly desired to do the right thing he would have reported it to military authorities. He perhaps would also raised his own voice during the event and said something...if his purpose was to stop such an event. He remains remarkably silent,yet very much well position for filming.
Why? That's not his job. His job is to record and report on the war. He did his job. Moreover, by simply reporting it as he did, he in effect, "reported it to military authorities".
"He perhaps would also raised his own voice during the event and said something...if his purpose was to stop such an event. He remains remarkably silent..."
If I was the Marine in question and the reporter interfered with an on-going operation in a hot zone, as you suggest, I would seriously considered, (a.)shooting him, (b.)arresting him or (c.)ejecting him from the area. The reporter's job is to report the news, not create the news.
While Sites didn't interfere with the ongoing operation, verbally or otherwise, he did add significant commentary to the video that explained the Marine's actions well enough that you would have thought that Sites was a defense attorney, not a reporter.
