Victims from the 2015 San Bernardino shooting are suing tech companies for neglect

Reuters/Mike BlakeLocal residents wait to return to their homes following a mass shooting in San Bernardino, California December 3, 2015.Surviving relatives of three people killed in the 2015 mass shooting in San Bernardino, California, are taking Facebook, Twitter, and Google to court, alleging they failed to clamp down on terrorist propaganda on their sites.

According to court documents cited by KABC-TV, the lawsuit alleges that the companies allowed people who sympathized with terror groups to spread propaganda, raise funds, and help recruit others.

"You see so much stuff on social media, that you wonder how that gets on there," said Gregory Clayborn, father of Sierra Clayborn, who was one of the 14 people killed in the December 2, 2015 attack. "And you say wait a minute isn't somebody monitoring or filtering or managing what gets on and what doesn't?"

Facebook defended its policies in a statement to KABC: "There is no place on Facebook for groups that engage in terrorist activity or for content that expresses support for such activity, and we take swift action to remove this content when it's reported to us," a statement read.

Twitter also claims that nearly 380,000 accounts were suspended for terrorist-related violations in the last six months of 2016, KABC reported.
