Facebook is urged to add "panic buttons" to its pages after the murder of a teenager was linked to the site. Jim Gamble, chief executive of Child Exploitation and Online Protection Centre (CEOP), said social networking giant didn’t agree to his demands outright at a meeting in Washington but he felt they were moving in the right direction. Speaking after a four-hour meeting, Gamble said Facebook was close to "doing the right thing" but urged the website to turn "words into action." "I felt that at the end of what were lengthy and at times tense negotiation we’re able to move towards a position. They’re one small step away from doing the right thing," said Gamble. "I am more optimistic than when I came. They aren’t saying no, that’s very clear. But they were equally direct and they came with their own agenda. "There’s no doubt they’re looking to improve their position around child safety and we recognise that. What I am looking for is turning words into action." The four hour discussion between Facebook and CEOP on Monday comes after calls for more security measures on the social networking site after the murder of a 17-year-old girl in the UK. The "panic button" proposed would allow younger users of the service to contact authorities such as CEOP or other anti-bullying support groups should they feel threatened.
