The image, believe, is of a dead youth in the background and a pair of young girls preening for the camera in the foreground.
He was paid by the photo used and the papers liked pictures of bodies.
He did take photos of car crashes and gangster shootings. And he was as likely to photograph the crowds looking at the grue as he was the event itself. I don’t recall photos of the crowds and the body in the same shot.
The world is also a bit different place. In the 1950s and 1960s, people would line up at a car crash on the highway to take a look. One of the educational filmmakers in Ohio even captured the spectacle and would shoot his own footage of the people dying at the scene (upclose and with sounds of their dying gurgles). Horribly exploitive (you can learn about it in the documentary “Hell’s Highway”). But so were the people who were stopping to gawk and the police who permitted it.
