Moral Panic
Moral panic is a feeling of fear to a large number of people. In the dictionary it defines it as 'the process of arousing social concern over an issue'. In Bowling for Columbine this is when the news talk about the incident when people took over the school and kept some people hostage after killing some students and teachers.
Mean World Syndrome
Mean World Syndrome was founded George Gerbner that describes violence content shown by the mass media that shows the audience that the world is more dangerous than it is. This happens every time something horrific happens in the world. The news just constantly show the story and nothing else and that happened for Bowling for Columbine.
