Hard and fast rules are impossible. Sometimes, for example, violent scenes are simply too shocking to show. On other occasions, it is the violence itself which makes the most telling point. On this occasion, however, the judgment should have been easy. Wearing a black tie as a mark of respect for those who have passed away is still a deeply ingrained custom in this country. You only have to go to a family funeral, as I did within the past week, to see how many people still hold to the practice. You only had to go to church on Easter Sunday to see, even there, how many people had put on black ties.
