 Facebook is facing backlash for bringing a virtual reality shooting game to a rightwing conference where the National Rifle Association (NRA) has promoted gun rights in the wake of a Florida school shooting. 
  
 The social media company, which has since removed the demonstration game and expressed “regret”, was already facing scrutiny for attending the Conservative Political Action Conference (CPAC), a high-profile event that featured speeches attacking gun control advocates and a renewed call from Donald Trump to arm school teachers.

 Hugo Barra, Facebook’s vice president of VR, said the company has a “standard set” of demos for events, including “action games” with “violence”. 
  
 “In light of the recent events in Florida and out of respect for the victims and their families, we have removed them from this demo. We regret that we failed to do so in the first place,” he said in a statement to the Guardian. 
  
 Hugo Barra (@hbarra) We removed the demo & regret failing to do so at the start. We got this wrong. Our demos come w a standard set of content, some are action games w violence. These shouldn't have been present, especially in light of recent events & out of respect for the victims & their families. 
  
 The conference in Maryland – which featured multiple NRA representatives and far-right French politician Marion Maréchal-Le Pen – came one week after a shooter with an AR-15 rifle killed 17 people in Florida, sparking a wave of student activism and renewed scrutiny of Republican politicians funded by the NRA. 
  
 Facebook, which has been criticized by some for giving money to CPAC, faced backlash Friday when video emerged of its Oculus demo game that appeared to involve rapid-fire shooting.

 Some criticizing Facebook also pointed out that its platform has played a role in spreading false conspiracy theories about survivors of the Marjory Stoneman Douglas high school shooting. 
  
  
  
 At CPAC, where Trump repeated his anti-immigrant rhetoric and attacks on Hillary Clinton, Facebook also set up a help desk and held a training for Facebook Groups. The groups feature has faced scrutiny over the last year for its role in helping neo-Nazis and rightwing extremists connect and organize.

 SAN FRANCISCO — Facebook pulled violent virtual reality games, including one in which players pretend to shoot people in a train station, from its booth at the annual Conservative Political Action Conference after public criticism. 
  
 Facebook's vice president of virtual reality, Hugo Barra, apologized for the demos of violent virtual reality games including "Bullet Train" during CPAC. 
  
 Criticism of the shooter game demo coming so soon after the shootings at a high school in Parkland, Fla., that left 17 people dead mushroomed on social media after a video of CPAC attendees playing the game using Facebook's Oculus virtual reality headset was posted on Twitter by NowThisNews reporter Sean Morrow. 
  
 "There is a standard set of experiences included in the Oculus demos we feature at public events. A few of the action games can include violence," Barra said in an emailed statement to USA TODAY. "In light of the recent events in Florida and out of respect for the victims and their families, we have removed them from this demo. We regret that we failed to do so in the first place." 
  
 CPAC — the annual conference for conservatives in Maryland where Wayne LaPierre, head of the nation's largest gun rights group, the NRA, spoke Thursday and President Trump spoke Friday — came one week after a shooter with an AR-15 rifle shot up Marjory Stoneman Douglas High School, sparking a wave of student activism. Facebook and Google have a presence at CPAC. 
  
 This is not the first time Facebook has been accused of being tone deaf in demonstrating the capabilities of its virtual reality. Facebook CEO Mark Zuckerberg apologized last year after live streaming a virtual reality tour of hurricane-ravaged Puerto Rico to promote Facebook's Spaces app. 
  
 At last year's annual Oculus Connect developers’ conference, Zuckerberg set an ambitious goal of getting 1 billion people to use virtual reality and said he wants to ensure the technology is "a force for good."

 Seriously, @facebook? You're at #CPAC demonstrating a VR shooting game? A shooting game? You should be ashamed. — Brent Andrew (@SanFranciscoBA) February 23, 2018

 Unless Facebook is charging CPAC attendees $5 to play & donating that money to gun safety organizations, this might be one demo to pull given circumstances... https://t.co/SLcIUINwzX — 👨🏻‍💻☕️🗽 (@hunterwalk) February 23, 2018

A:
Facebook has apologized for featuring a virtual-reality game called Bullet Train—in which players shoot people at a train station—in its booth at the Conservative Political Action Conference, USA Today reports. Bullet Train was just one of a number of violent games featured at the Facebook booth. "In light of the recent events in Florida and out of respect for the victims and their families, we have removed them from this demo," says Huga Barra, Facebook vice president of virtual reality. "We regret that we failed to do so in the first place." According to the Guardian, Facebook faced public backlash after video of the Bullet Train demo was posted to social media Friday. "Seriously, Facebook?" reads one tweet. "You're at CPAC demonstrating a VR shooting game? A shooting game? You should be ashamed." But it wasn't just violent virtual-reality games. Facebook is facing criticism for participating in CPAC—to which it has given money—at all. Multiple NRA representatives, including CEO Wayne LaPierre, spoke at the event, which also featured a far-right French politician. Some critics pointed out that Facebook has played a role in spreading conspiracy theories about the survivors of the Parkland shooting. Kira Lerner, a reporter at ThinkProgress, tweets that two CPAC attendees told her they saw proof on Facebook that Marjory Stoneman Douglas High School students were crisis actors. “Facebook routinely participates in events hosted by organizations across the political spectrum,” a Facebook spokesperson says. “Our involvement is not an endorsement of any particular position or platform.”
