I read about this incident too - and the apparent attempts to minimize/cover up afterward. It was probably as sickening and disgusting a story as I've seen for a long time. Just focusing on the social media aspects of the story, though... it always astonishes me that people would film themselves in the act of doing something which is illegal, immoral, and so repugnate that most people would be nauseated by the behavior. Then to tweet it or post it on social media? It leaves me scratching my head. But if your moral code is so twisted, and your ability to feel empathy is so low, it could be that it wouldn't occur to you that other people might be horrified rather than amused or impressed? I don't know.
