Following the shooting at YouTube's headquarters in San Bruno, California, yesterday, the company has announced plans to increase security at all of its offices worldwide. YouTube says this is intended to "make them more secure not only in the near term, but long-term." The Verge reports: The move reflects a growing concern in Silicon Valley that the effects of increasingly toxic and partisan online behavior may translate into violent offline actions. YouTube's statement was released through Google's Twitter account for communications; it's not clear whether Google itself will be implementing stronger security measures beyond YouTube. The shooter, 39-year-old Nasim Aghdam of San Diego, died yesterday of a self-inflicted gunshot wound after shooting and injuring three employees. From police reports, testimony from Aghdam's family members, and extensive traces of the woman's online behavior on YouTube and other platforms, we now know that Aghdam was disgruntled over the demonetizing of her videos and harm to her financial well-being.
