Viral clips of murder may help drive contagious copycat killings

The shareability of violent videos like that of the Virginia news shooting may contribute to future crimes – and they may be getting more clickable

IT IS now possible to watch footage of someone being murdered on your Facebook feed, sandwiched between a holiday sunset selfie and a cat playing the piano. That’s not just bizarre and unpleasant: it could encourage people to commit such acts more often.

The latest shareable carnage is the killing of Virginia local television reporters Alison Parker and Adam Ward, who were shot last Wednesday by a former colleague. After the murder, the shooter orchestrated a full social media publicity roll-out, including a , before killing himself a few hours later. The shooter’s Twitter profile accrued more than 23,000 followers, the video went viral on Facebook and was compressed into shareable gifs for easier dissemination.

Some considered sharing these images . “Our society unfortunately needs vivid reminders of the awesome, life-stopping power of firearms,†website.

But research so far suggests that might not be such a good idea.

There is already strong evidence that suicide is contagious, and this has led many media outlets to . “Research shows a ,†says at the University of Exeter, UK.

Does media coverage make people more likely to commit murder, too? Although some shooters, including the one in Virginia, cite previous incidents as inspiration for their crimes, research has so far been lacking, partly due to a general resistance to gun control in the US (see “Shhh! Don’t mention the killing“). Now, the , has found that they, too, are contagious (PLoS ONE, ).

at Arizona State University in Tempe and her colleagues investigated the patterns in these events using a model previously used to describe the spread of epidemic diseases, , and earthquake aftershocks. They found that the occurrence of a mass killing – which they defined as the death of four or more people – meant that another shooting was significantly more likely to happen within the next 13 days.

“The occurrence of a mass killing makes another more likely to happen within the next 13 daysâ€

The body count of a given shooting is not important in itself, Towers suggests. It is whether a shooting receives local or national news coverage. “It’s the attention, not the numbers,†she says. The reason for this, she thinks, is that an event reported in the national media is able to reach the very limited population that might potentially commit a copycat crime.

“There aren’t many people susceptible to this contagion, maybe one in a million,†she says. “You have to have a psychological ‘immune system’ that is vulnerable to being infected by these kinds of imagesâ€, the way people with compromised immune systems catch the flu. To do this, a story has to go national.

Towers’s research did not distinguish between traditional and social media. But other studies indicate how social sites can give a story national reach even without official media coverage. For example, Facebook’s reach dwarfs that of any traditional media channel: making something go viral with Facebook’s 1.49 billion members does not depend on a national news organisation deeming it newsworthy.

So social media gives the means, but why do people transmit this material? Why did people share the video of the Virginia shooting, or the videos and manifestos posted by the , or the horrific images and videos broadcast by ISIS?

There is evidence that social media not only makes it easier to spread information, but it changes the dynamics of its spread. A clue to why this might be so comes from research into how we interact with others online. In our daily lives, we generally adapt our behaviour according to the social situations we find ourselves in. But online, these various aspects of our persona flatten into a single public face – a phenomenon known as . Could information itself be subject to a similar flattening?

The Facebook feed already collapses gossip, advertising, entertainment, world news and games into a single homogenised stream of content. That could make it easier to share without thinking too hard about it, says social media researcher at Microsoft Research.

“They share because they’re affected by what they see,†she says. “They aren’t thinking about the context in which their post will appear. They aren’t thinking about how publicity is desired by those producing the videos. They are thinking about their own emotions and the people they know who they think need to know.â€

More ominously, it might be that we share horrifying content because its producers are getting better at packaging it. Research has shown that gossip is king on social media, and advertisers, marketers and publishers quickly cottoned on and changed the way they presented information. Thomas Poell at the University of Amsterdam in the Netherlands says this explains the success of headlines like “You won’t believe what happened next†and “One weird trickâ€.

His research suggests activists learned from marketing. “Our main conclusion is that social platforms strongly focus public attention on the spectacular, comical and violent aspects of protest,†he says (Information, Communication & Society, ).

Shooters and ISIS have turned the social media activism model to their advantage. “Obviously these people are not similar to activists,†Poell says. “But some of the mechanisms we have identified in our research on activist social media communication do play a role.â€

Once virality hits a certain threshold, the number of people reposting content overwhelms any human attempts to review and censor them. Facebook and Twitter removed the Virginia gunman’s account within minutes, but it was too late. The video of Parker and Ward’s last moments will likely never be scrubbed from the internet.

So as with suicide, so for murder. Whether through traditional media or social share, viral popularity moves the spark one step closer to the powder keg.

And if that video does pop up in your Facebook feed? “Watching is up to the individual,†says Towers. “But it’s worth remembering that you can never unsee something.â€

Shhh! don’t mention the killing

It’s not every day that a scientist undertakes ground-breaking research with no funding at all. But that’s what Arizona State University statistician Sherry Towers had to do in order to produce the first study on the contagion of mass shootings in the US (see main story). “We basically had to do this in our spare time,†she says.

That’s because since 1997, the US Congress has restricted research into mass shootings. A bill passed in 1996 stipulated that no Centers for Disease Control and Prevention funding could be used to advocate or promote gun control. This was vague enough to ensure that research into the effects of gun violence has never been funded since.

The idea for the study struck Towers when a meeting at Purdue University was cancelled due to a school shooting there. “I thought, wait a second, this is the fourth shooting [in the US] this week,†Towers says. Was this merely a blip, she wondered, or were these events becoming more frequent?

A national database recording all shootings would make it easier to find out, but the funding restrictions also apply here. However, a released last month did conclude that mass shootings are on the rise and highlighted the need for more research to inform policymakers.
