Theory

Coined by the sociologist and researcher, David Phillips, this theory is an extension of "cultural contagion" and "

. This theory indicates that through the publicity received from acts of mass murder, perpetrators of this type of criminal act have a fundamental aim of achieving fame or notoriety. Sociologists who have engaged with this theoretical study proposes that the 'contagion' aspect of this theory increases the probability that a similar shooting incident will occur, inspired consciously or subconsciously by other rampage shooters. This theory suggests that the increased occurrence of global gun-related crime is linked to the role of mass media platforms in broadcasting and circulating content about this type of criminal behaviour, particularly through public dissemination of the active shooter's identity.

and distortion establish a perception of shootings as frequent and recurrent. However, data indicates that mass shooting incidents take the fewest lives out of all subcategories of homicidal crime, but are among the largest portion of crime reported in the media, with recent studies indicating that approximately 50% of news reporting focuses on the broadcasting of violent crime alone. Despite taking the fewest lives among all acts of homicide, the broadcasting of mass shootings yields the capacity to create widespread panic due to their occurrence in a public setting, approximate 24-hour or less time frame, and random selection of victims. Numerous studies conducted by the Federal Bureau of Investigation and the Advanced Law Enforcement Rapid Response Training (ALERRT) research team use statistics from historical shootings as case studies to determine the nature of media coverage and research effects of this media broadcasting to formulate preventive measures.


Definitions


Mass shooting

Mass shooting There is a lack of consensus on how to define a mass shooting. Most terms define a minimum of three or four victims of gun violence (not including the shooter or in an inner city) in a short period of time, although an Australian study from 200 ...
refers to a firearm-related incident occurring in a public setting, resulting in the death of three or more people within one event. Although occurring globally, majority of mass shootings occur in the United States, with five of the most fatal incidents in their national history occurring from 2007 onwards. According to contemporary research, a 'mass shooting' is defined as (1) the perpetrator committing an act of mass homicide in a 24-hour period, (2) use of a fire-arm and, (3) the motive of the shooting having an absence of a

or terrorist-group affiliation. Mass shootings usually occur in a public setting, however, in recent history, numerous shootings between 1990–2018 in the United States have taken place in schools. A contemporary study conducted by the
Federal Bureau of Investigation The Federal Bureau of Investigation (FBI) is the domestic intelligence and security service of the United States and its principal federal law enforcement agency. Operating under the jurisdiction of the United States Department of Justice, ...
revealed that between 2016–2017, fifty active shooting incidents occurred in 21 states, with approximately 943 casualties (221 people murdered and 743 severely injured). Twenty of those incidents met the defining parameters of a 'mass killing'. Mass shootings warrant global concern with recent figures reflecting that, on average, a mass shooting in the United States will occur every 12–13 days, with school shootings occurring an average of every 32 days. Of these incidents, a mimicked shooting will occur within an estimated 2 week period.


Copycat effect

The term "copycat effect" refers to the replication of any violent offence, a sub-categorical theory that is closely related to the study of "mass shooting contagion". Although
copycat crime A copycat crime is a criminal act that is modelled after or inspired by a previous crime. It notably occurs after exposure to media content depicted said crimes, and/or a live criminal model. Copycat effect The copycat effect is the alleged tende ...
is similarly influenced by media coverage of mass violent crimes, this term refers to the potential for mimicked criminal behaviour. Distinguishing these theories, 'mass shooting contagion' theory indicates that all forms of media coverage of mass homicidal events, such as televised coverage, radio broadcasting, editorial and more recently, social media circulation, have a culminated effect in influencing the rise of these crimes. The copycat effect not only relates to the potential emulation of violent offences, however, is used to describe the mimicking of famous criminals themselves, with aims to receive a similar type of fame and social influence.


Media coverage of mass killing

New broadcasting of mass shooting coverage informs the public about aspects of the incident, such as the location, number of casualties, nature of the crime and potentially, identity of the perpetrator. A report released in 2017, 'Dear Members of the Media' urges news reporters to cease publication of names, photos and other forms of identification to limit the potential for mass shooting contagion. Research assessing the effects of violent media in correlation with aggressive behaviour suggests that heightened viewing of murderous media creates an imitative influence on criminal behaviours. According to

researcher, Jennifer L. Murray, reporting of mass shooting is reported in seven, cyclical stages: (1) tragic shock, (2) first witness reports, (3) identification of shooter, (4) reports of character of shooter, (5) media branding: the packaging of a massacre, (6) official response and official report and (7) tragic shock. With media outlets reporting news within a 24-hour news cycle, the capacity for mass shooter's identity to become a focal point of news media increases.

Columbine High School

The shooting at

in 1999 remains one of the most referenced shootings in US history, with studies indicating that an estimated 10,000 articles were published following the incident. Another study found that in the year that the Columbine shooting occurred, approximately 319 stories about the incident were aired in evening news broadcasts. The Columbine shooters,
Eric Harris and Dylan Klebold Eric David Harris (April 9, 1981 – April 20, 1999) and Dylan Bennet Klebold (; September 11, 1981 – April 20, 1999) were an American mass murder duo who perpetrated the Columbine High School massacre on April 20, 1999. Harris and Klebold ...
, expressed their desire for worldwide recognition in ‘basement tapes’ recorded prior to the mass homicide, stating that they aimed for “The most deaths in U.S. history…We’re hoping. We’re hoping.” These tapes circulated numerous media outlets, with stations such as

airing coverage of the aftermath of the incident for over a 6-hour period. A study conducted in 2015 suggest that the Columbine shooters inspired a minimum of 21 mimicked shooting and 53 attempted plans to commit such an act in the U.S. over a 15-year period.


Sandy Hook Elementary School

The Sandy Hook Elementary School shooting killed 27 people, numerous media outlets covering the event by focusing on the shooter's identity, connections with the school and relationship with family members. The Sandy Hook shooter, Adam Lanza, was active in online commentary about U.S. mass shootings, posting in forums about his studies into the personality, and characteristics of mass shooters, once posting a spreadsheet which contained over 500 rampage shooters. Minutes following the mass shooting, media coverage of the event began. Misinformation in the media resulted in numerous media outlets identified the shooter as Adam Lanza's brother, resulting in the circulation of pictures and video footage sourced from Ryan's social media. Investigations conducted by the FBI's Behaviour Analysis Unit found that the Sandy Hook shooter had begun investigation into active shooters in U.S. history in 2011, with the search indicating that infatuation and primary inspiration for his mass homicide included the Columbine, and Virginia Tech shooters.


Tucson

. Posting online prior to the shooting incident, the Tucson shooter said "I'll see you on National T.V.!" and continued with "I have this huge goal at the end of my life: 165 rounds fired in a minute!" Although many media outlets published information about the mass shooting and identification of the offender, coverage focused primarily on debate surrounding reforming gun control laws within the United States.


Virginia Tech

The 2007 Virginia Tech shooting received widespread media attention immediately following the incident, with a death toll double that of the Columbine shooting. A study conducted in 2007 by
Pew Research Centre The Pew Research Center is a nonpartisan American think tank (referring to itself as a "fact tank") based in Washington, D.C. It provides information on social issues, public opinion, and demographic trends shaping the United States and the wor ...

A 2017 study found that 32 perpetrators of mass homicide identified the Columbine shooters as role models in mimicking their attack, whilst the Virginia Tech shooting inspired 8 mass shooting attempts. The Virginia Tech shooter made reference to the Columbine shooting in his video manifesto prior to the act of mass murder, and said he wanted to "repeat Columbine" while in school.


Aurora

The Aurora movie theater shooting in 2012 is recognized as the third most referenced shooting in United States history, resulting in the death of 12 and 58 others severely injured. The shooting instigated the ‘No Notoriety’ movement, with parents of a shooting victim, Tom and Caren Teves pushing for media outlets to limit coverage of homicide events to why and how the crime was committed. Coverage of the shooting focused primarily on gun control laws, with 14 references made towards improving gun control and access policies, found in a total of 12 articles. Despite majority of media focus oriented around gun laws, this type of stricter fire-arm related legislation has yet to be enacted, instead indicating that the broadcasting of this shooting inspired the shooter of Sandy Hook Elementary in 2012.


"Don't Name Them" Campaign

The "Don't Name Them" campaign is a movement founded by the Advanced Law Enforcement Rapid Response Training Centre (ALERRT), that encourages news corporations to avoid coverage that focuses on mass shooter's identity, motives, declared manifesto and history. Outlined by a recent report from the FBI's Behavioural Analysis unit, media coverage of mass shooting incidents "cements the legacies they seek to achieve" by providing global attention and fame. An extension of the "No Notoriety" campaign founded by Tom and Caren Teves following the shooting in Aurora, Colorado, the "Don't Name Them" movement recognizes that the expression of "all publicity is good publicity" can account for the
