"I would always do it as we're walking around and it was natural. I wouldn't go to police stations. It was just things where I happened to be walking the streets. I would see an officer and I would just ask for a picture," Matt told me via phone from his hotel in Fiji.
"Sometimes there would be a language barrier," he told me.
He'd use Google translate to communicate, and after he had compiled enough photographs, he was able to show offices the existing images—they would quickly get an understanding of what he was asking for.
"I would show them the photo of the two police officers on top of Machu Picchu, or of the two officers in front of the Taj Mahal," he said.
Matt described one day when he was walking the streets in Guayaquil, Ecuador, when he encountered a police officer standing in front of their main cathedral in that city. After navigating the language barrier with a combination of Google translate and some example photos, the officer agreed to be pictured.
