In 2017, the family of a California man killed in the Barcelona terror attack filed a lawsuit against Google, Facebook and Twitter. The family brought suit under JASTA, alleging the tech companies played a role in “aiding, abetting and knowingly providing support and resources” to the Islamic State group responsible for the attack.
The assault, which occurred on Barcelona’s most popular boulevard, Las Ramblas, was the country's worst terrorist attack in over a decade, resulting in 13 people dying and 130 injured. A vehicle, driven by a member of the Islamic State group, plowed into pedestrians. The complaint argues that the three tech companies, have “for years knowingly and recklessly provided the terrorist group ISIS with accounts to use its social networks as a tool for spreading extremist propaganda, raising funds and attracting new recruits.”
