San Diego Mosque Shooting: Pattern of Extremist Violence Inspired by Viral Content

One brutal video shot in a first-person shooter (FPS) style reveals the horror of the attack at the Islamic Center of San Diego on Monday. The video, confirmed authentic by US federal law enforcement officials, shows one attacker’s viewpoint as they storm the mosque, open fire, and eventually take their own life. The attack was carried out by two teenagers, Caleb Vazquez, 18, and Cain Clark, 17, who police say met online. The tragedy adds to a long list of patterns of bloodshed inspired by online extremist content, where violence is recorded deliberately to be consumed and archived online. Investigators found a manifesto believed to be written by the two perpetrators. In the document, they say they were inspired by Brenton Tarrant, the Christchurch mass shooter who killed 51 people in 2019. Tarrant filmed his attack live on Facebook, a moment that experts have described as a landmark in the gamification of mass murder. Ironically, one of the victims of the San Diego attack was Amin Abdullah, 51. Abdullah chose to become a security guard at the mosque because he was deeply disturbed by the Christchurch massacre of 2019. He died while trying to return fire at the attackers to protect other worshippers. Adrian Shtuni, a security consultant at the International Centre for Counter-Terrorism, explained that using a video game-like perspective is a deliberate attempt to attract young audiences accustomed to that digital aesthetic. ‘This is not just about ideology, but also about ego, status, and fame. They are pursuing a terrifying form of immortality through viral digital footage that is hard to remove,’ Shtuni said. The attackers’ weapons and tactical gear were also adorned with neo-Nazi symbols such as Sonnenrad and the swastika, as well as the inscription Race War Now. The San Diego attack video briefly circulated on the Discord communication platform before spreading to X (formerly Twitter), Reddit, and 4chan. Although tech companies signed the Christchurch Call international agreement to curb the spread of extremist content, the speed of virality and the use of private messages remain major challenges. Jared Holt, a senior researcher at Open Measures, warned that extremists record such acts in the hope of inspiring others to do the same. In the radical right wing ecosystem, they often refer to perpetrators with the highest score as heroes or saints. The FBI said the perpetrators’ manifesto shows hatred toward various races and religions. ‘These subjects discriminate not whom they hate,’ said Mark Remile, the FBI special agent leading the investigation. Authorities are continuing to trace the pair’s digital footprints to understand how their radicalisation occurred, including in online schools and forums. (Washington Post/I-2)
