Supreme Court protects Twitter and Google in high-profile social media cases.

The US Supreme Court has ruled in favor of Google and Twitter in two cases that alleged social media liability in terror attacks overseas. The court found that the families of victims of the attacks did not adequately show that the online platforms had "aided and abetted" the terrorists in violation of federal law. The victims' families alleged that the social media companies were indirectly complicit in the attacks by failing to remove extremist content from their platforms which in turn may have aided terrorist radicalization and recruitment. The decisions are a substantial victory for online companies which had warned that expanding the scope of liability would upend the internet as we know it.
