Now that the election is over we can return to more traditional and less stressful forms of entertainment, like murder. When the evenings draw in and the temperature falls with the leaves, there’s nothing as comforting as a good murder. The actual homicide rate in America has been going down for a long time, but in movies and on television it has gone the other way. Movies were always violent, ever since the earliest cowboy epics. Now they are more violent by far. By the age of 18, according to Mr. Google, the average citizen has watched 40,000 murders on the small screen.
