This fascination with death and interaction with media editorial policies sometimes has problematic consequences for public policy. For example, Vincent Sacco and others described how the mainstream commercial media in the United States changed their editorial policies in the 1970s to focus more on the police blotter. The human psychology behind "If it bleeds, it leads" meant they could retain or even increase their audience while reducing the cost of producing the news: Investigative journalism is enormously expensive, especially if it offends a major advertiser. Focusing on crimes apparently committed by people without substantive political or economic power is cheap.
