According to Camilla Griggers, professor of Visual Communication and Linguistics at California State University Channel Islands:

The Army photographer, Ronald Haeberle, assigned to Charlie Company on March 16th, 1968 had two cameras. One was an Army standard; one was his personal camera. The film on the Army owned camera, i.e., the official camera of the State, showed standard operations that is, 'authorized' and 'official' operations including interrogating villagers and burning 'insurgent' huts. What the film on the personal camera showed, however, was different. When turned over to the press and Government by the photographer, those 'unofficial' photographs provided the grounds for a court martial. Haeberle's personal images (owned by himself and not the US Government) showed hundreds of villagers who had been killed by U.S. troops. More significantly, they showed that the dead were primarily women and children, including infants. These photographs exposed the fact that the 'insurgents' in popular discourse about Vietnam were actually unarmed civilians. The photos made visible to viewers that the 'enemy' in Vietnam was actually the indigenous Vietnamese population.^[1]

According to John Morris, the photo editor for The New York Times at the time, Haeberle claimed that the images on his personal camera were his own copyright, but the Times and other publications printed them without payment in the "public interest", and also arguably in the public domain, produced by the U.S. Army:

Haeberle's pictures were arguably government property... In late morning, we received word that London papers, copying the photos from The Plain Dealer, were going ahead without payment, ignoring the copyright. The New York Post followed, in its early afternoon edition. Rosenthal decreed that it would now be ridiculous for The Times to pay. We would publish "as a matter of public interest.^[2]
