The post, a few back, by Panzade provided some context to me -
I've no idea about Orkin's intent. The comment that Jinx Allen was the model is ambiguous to me, relative to how much the shot was or was not planned, in Orkin's mind or between the two of them beforehand. Piazza della Repubblica is often a busy place and like Orkin, I've turned around and gone back to shoot something I'd already passed through after it registered while I was walking. For me, spontaneously, but I don't know Orkin's mind. Which tells me I need to read up.
It might have been what we now think of as a political move - more likely to me, it was capturing experience. Or, both, nascent political.
