据哥伦比亚广播公司新闻对袭击 footage 的分析，周一圣地亚哥伊斯兰中心袭击事件中，枪手拍摄自己杀害三人并最终自尽的直播画面期间，至少有三人进行了观看。其中一名观众曾敦促另一名观众报警，但目前尚不清楚是否有人采取了行动。
袭击的录像后来在网上流传，其中包括在所谓的“血腥网站”上——这些网站此前曾是大规模枪击事件崇拜者的聚集地。
根据哥伦比亚广播公司新闻审核的屏幕录像，袭击发生前及发生期间，枪手与一个仅被识别为“诺埃尔”的用户进行了Signal视频通话。录像显示，诺埃尔在枪手开始射击前，已经与他们通话了约20分钟。
在此期间，诺埃尔似乎用另一部手机加入了与另一名被识别为“奥托”的用户的Discord视频通话，并调整了摄像头角度，让奥托可以实时观看Signal通话画面。据哥伦比亚广播公司新闻审核的录像显示，奥托随后用自己的设备进行了录制。
随着袭击展开，奥托在Discord上向另一名用户提醒这场直播。“伙计们快看，”奥托写道。对方询问枪手的位置。“在某个清真寺[原文拼写错误]，”奥托回复道。
“让她打电话报警，”那人写道，显然是指诺埃尔。“兄弟，让她打电话报警，”一分钟后他又写道。“就算他们不在洛杉矶也没关系，告诉她报警，警方或许就能查到他的位置。”
五分钟后奥托回复时，袭击已经结束。其中一名未成年枪手、17岁的凯恩·克拉克开枪打死了另一名18岁的迦勒·巴斯克斯，随后举枪自尽。这一系列过程也被视频记录了下来。

哥伦比亚广播公司新闻无法独立核实观看视频的用户所在地，不过录像中可见的细节表明，其中一些人可能距离袭击发生地加利福尼亚州很远。
在奥托的屏幕录像中，设备上显示了阿尔巴尼亚移动运营商VodafoneAL，手机时区与阿尔巴尼亚当地时间一致，这表明奥托可能在海外观看了直播。诺埃尔设备上显示的时区比圣地亚哥快三小时，暗示该用户可能身处东部时区。
战略对话研究所的数字研究分析师巴雷特·盖伊审查了枪手、诺埃尔以及其他似乎与他们有关联的人的线上活动后表示，诺埃尔似乎与其中一名枪手存在某种线上恋爱关系。该组织高级研究经理马修·伊万诺维奇表示，两名枪手都在主流社交媒体平台的边缘社区活跃。
据哥伦比亚广播公司新闻此前报道，当局认为实施袭击的两名青少年是在网上结识的，发现两人都居住在圣地亚哥地区后才线下见面。
两人在一份被联邦调查局称为“宣言”的文件中，宣扬了反犹太主义、反穆斯林、厌女症、反西班牙裔、反同性恋和反跨性别仇恨的虚无主义混合论调。这份文件以反犹太主义咆哮开篇，反复出现“都是犹太人的错”这句话。他们似乎将自己称为2019年新西兰基督城清真寺枪击案凶手的“儿子”——该案件造成51人死亡，凶手同样对袭击进行了直播。
Discord周四表示，已保留与此次袭击相关的信息并透露给执法部门，并将继续与当局密切协作。
“我们与圣地亚哥社区一同悲痛，向受害者家属和所有受这场悲剧性暴力影响的人表示哀悼，”Discord的一位发言人说道。“Discord强烈谴责暴力行为，我们有严格的政策禁止任何人支持、宣扬或参与暴力行动。我们未发现此次事件的直播起源于Discord的证据。”
Signal拒绝置评。
这起案件引起了追踪网络平台如何审核暴力内容的研究人员的关注。
“圣地亚哥的袭击再次致命地提醒我们，美国的任何威胁评估都必须考虑到我们日益严重的暴力问题，以及真正助长这种暴力存在的网络平台，”反诽谤联盟极端主义对策与情报高级副总裁奥伦·西格尔说道。
西格尔表示，越来越多的袭击者如今会在准备武器的同时准备直播和宣言，称这是虚无主义暴力极端主义亚文化的一部分。
“在美国，你当然可以随心所欲地表达仇恨，我们的言论自由保护这样做的权利，”西格尔说道。“但当我们看到一起又一起针对宗教机构和学校的暴力事件，背后都有一条共同线索：一些网站将这种行为正常化，而包括这些袭击者在内的攻击者会向这些在线社区发出信号，这让我们不禁质疑，我们是否需要在法律或其他方面对他们采取更强硬的立场。”

Several people watched San Diego attack live on video calls, recordings show

At least three people watched a livestream as gunmen filmed themselves killing three people in Monday’s attack at the Islamic Center of San Diego before their own deaths, according to a CBS News analysis of footage from the attack. One viewer urged another to alert law enforcement, but it is not clear if anyone did.
A recording of the attack later circulated online, including on so-called “gore websites” that have previously served as gathering places for admirers of mass shooters.
According to screen recordings reviewed by CBS News, the shooters were on a Signal video call with a user identified only as “Noelle” before and during the attack. The recordings show Noelle had been on the call with the gunmen for roughly 20 minutes before they began shooting.
During that time, Noelle appears to have used a second phone to join a Discord video call with another user, identified as “Otto,” positioning the camera so Otto could watch the Signal call in real time. Otto then began recording on his own device, according to footage reviewed by CBS News.
As the attack unfolded, Otto alerted another person on Discord to the live video. “DUDE LOOK,” Otto wrote. The person asked where the gunmen were. “IN SOME MOSUQE [sic],” Otto replied.
“Tell her call the cops,” the person wrote, in an apparent reference to Noelle. “Bro, tell her call the cops,” they wrote again a minute later. “It doesn’t even matter if they aren’t in LA just tell her to call them and they can hopefully find out where he is.”
By the time Otto responded five minutes later, the attack was over. One of the teen gunmen, Cain Clark, 17, had shot and killed the other, 18-year-old Caleb Vazquez, before turning the gun on himself. That sequence was also captured in the video.

CBS News could not independently verify the location of the users who watched the video, though details visible in the recordings suggest some of them may have been located far from California, where the attack occurred.
In Otto’s screen recording, VodafoneAL, an Albanian mobile carrier, appeared on the device, and the phone’s time zone matched local time in Albania, suggesting Otto may have watched from overseas. A time zone visible on Noelle’s device was set to three hours ahead of San Diego, suggesting the user may have been in the Eastern time zone.
Noelle appeared to be in some kind of online relationship with one of the shooters, according to Barrett Gay, a digital research analyst at the Institute for Strategic Dialogue, who reviewed the online activity of the shooters, as well as Noelle’s and others who appeared connected to them. Both shooters had been active in fringe communities on mainstream social media platforms, said Matthew Ivanovich, a senior research manager at the organization.
Authorities said they believe the two teens who carried out the attack met online and discovered they were both residents of the San Diego area before meeting in person, CBS News previously reported.
The pair shared a nihilistic mix of antisemitic, anti-Muslim, misogynistic, anti-Hispanic, anti-gay and anti-trans hate rhetoric in what the FBI called a “manifesto.” The document opens with an antisemitic rant repeating the phrase “IT’S THE JEWS.” They appear to refer to themselves as the “sons” of the perpetrator of the 2019 mass shooting at a mosque in Christchurch, New Zealand, that killed 51 people, who also livestreamed his attack.
Discord said on Thursday it had preserved information related to the attack and disclosed it to law enforcement, and that it would continue to work in close coordination with authorities.
“We share in the San Diego community’s grief and extend our condolences to the families of the victims and to everyone impacted by this tragic violence,” a spokesperson for Discord said. “Discord strongly condemns violence and we have strict policies against anyone who supports, promotes, or engages in violent acts. We found no evidence that the livestream of this event originated on Discord.”
Signal declined to comment.
The case has drawn attention from researchers who track how online platforms moderate violent content.
“The attack in San Diego is another deadly reminder that any threat assessment in this country has to account for the increasing violence that we’re seeing and the online platforms that really enable this to exist,” said Oren Segal, senior vice president of counter-extremism and intelligence at the Anti-Defamation League.
A growing number of attackers now prepare their streams and manifestos alongside their weapons, Segal said, calling it part of the subculture of nihilistic violent extremism.
“Certainly in America you can be as hateful as you want to be. We have that protection for freedom of speech here,” Segal said. “But when we see incident after incident of violence against religious institutions and at schools that have a through line, which is a set of websites that normalize this in which the attackers, including these attackers are signaling back to these online communities, it makes you wonder whether we need to take a much harder stance legally or otherwise against them.”
