School Shootings are typically reported episodically rather than thematically, as if they were 'one of a kind' events rather than events occurring at a relatively constant rate. American news coverage typically elides what is most common about them: that they are the product of easy legal access to firearms in the United States. It is much less difficult to obtain a firearm in the United States than in any other wealthy democracy. As a consequence, many more atrocities committed with firearms occur in the United States. To avoid discussing gun violence as a social problem, something that would elicit expressions of outrage from the politically powerful Gun Lobby, reporters and editors focus most news coverage on the psychology of the killer.
