This assessment is about right. Watching the clip of him taking the phone and being called out on it, what came across was him desperately trying to think what he was supposed to do, before taking the phone out of his pocket and pretending to look with concern at the picture. He wasn't expecting the journo to reveal that he had taken the phone and put it in his pocket. He assumed that his status was such that the journo would have to accept this, and so he was genuinely fazed when the lad didn't act as expected.
He had no genuine reaction about the child. His only concern was about trying to assess what part he was meant to play, what reaction he was supposed to feign, what emotion he should pretend to feel. Trying to retrieve from his memory what other people had done in similar situations, and what might work to get him through the next 30 seconds.
Psychopath.
