Paris attacks in 2015
The father of Cal State Long Beach student Nohemi Gonzalez, the only American killed in the November 13, 2015, Paris massacre, files suit in San Francisco, California, federal court against Twitter, Facebook, and Google, alleging the companies provided "material support" to the Islamic State and other extremist groups. While generally free of liability under U.S. law which provides a legal "safe harbor" for content posted, this case targets the behavior social media companies enable. The suit is very similar to a case brought against Twitter in January by the widow of a contractor killed in the November 9, 2015, attack in Jordan.
