Silicon Valley firms halted spread of Steven Sotloff beheading video

Stephen Balkam, CEO of the Family Online Safety Institute, comments of the recent posting of beheading videos on social media: “It’s been very interesting, with this second beheading, how very little of those images have been passed around,” said Family Online Safety Institute CEO Stephen Balkam, who serves on Facebook’s safety advisory board. “It’s very difficult to find them unless you know of some darker places on the web.”
