This is horrific and infuriating — my heart goes out to the families and to the Muslim community terrorized by this attack. If the allegations are true that a teen filmed the massacre and helped publish the shooters’ manifesto, that goes beyond passive complicity: amplifying and memorializing racist violence is part of how these movements recruit and spread. Prosecutors should pursue accountability, but we also need to be honest about the bigger picture that made this possible. We can’t treat this as an isolated “monsters did this” story. The shooters’ arsenal, the apparent access to guns in a home, and the clear influence of white supremacist manifestos point to multiple systemic failures — lax gun storage and access, online spaces that radicalize and glorify violence, and real-world communities that normalize racist ideology. Holding individuals criminally responsible is necessary, but it must be coupled with stronger safe-storage laws, comprehensive background checks, red-flag enforcement, and concerted efforts to root out extremist organizing online. Tech platforms share responsibility too. Livestreaming killings and republishing manifestos is precisely what these perpetrators want: attention, recruitment, amplification. Platforms must do more to stop the spread of violent material and disinformation while respecting rights — quicker takedowns, better detection, and clearer accountability for repeat offenders and those who knowingly distribute terror content. Finally, we need prevention and solidarity. Invest in anti-radicalization programs, mental-health and community supports for young people, and education that counters hate. And while seeking justice, we must center support for survivors and the mosque community, protect vulnerable religious minorities, and refuse to let this violence be normalized or repeated.
