Descriptions of school shootings through narration. The footage is limited, but the descriptions of the murders against children are graphic and upsetting.

Frightening for anyone who lives in or wants to visit America, as the film argues it is a country with an alarming rate of violence and anarchy.

A murderer is interviewed and discusses interacting with the severed heads of his victims. It's incredibly confronting to hear.
