Why didn't he simply show the captain the photos that were on his iPhone? That would have verified that he only took one photo, and it violated no one's privacy. Actually showing the photos would have been a stronger argument than saying "That is a lie." Also, he could have volunteered to delete the one photo that he took. Someone in the comments suggested that this is a "he said, she said" situation. Not really, because there was a camera involved. The camera is the authority on the subject of whether he took photos that he should not have taken. I recently was at the Port Authority, in New York City. I was amazed at how busy it was at rush hour, so I pulled out my iPhone and took some pictures. I did not realize this was forbidden. A policeman approached me immediately and asked me what I was doing. I showed him the photos I had just taken and I explained I wanted to send them to some friends who had never visited New York. He suggested that I delete the photos but he walked away without making me do anything, so I was able to keep the photos.
