Fantastic. I've been waiting to see these cases.
Start with a normal person, get them all jacked up on far right propaganda, then they go kill someone. If the website knows people are being radicalized into violent ideologies and does nothing to stop it, that's a viable claim for wrongful death. It's about foreseeability and causation, not about who did the shooting. Really a lot of people coming in on this thread who obviously have no legal experience.
