Mark Zuckerbeg

Speaking on stage at Techonomy, a technology conference in California, Mr Zuckerberg said Facebook should not be held responsible.

"The idea that fake news on Facebook influenced the election in any way is a pretty crazy idea," he said.

"If you believe that then I don't think you have internalized the message Trump supporters are trying to send in this election."

The video was taken down by Facebook for which they later blamed a technical glitch as the reason. Facebook’s act has been criticised on a global level.

News about manhunt by police officers is now a common sight on various media platforms. Be it the Alton Sterling shooting case in Baton Rouge, Louisiana or the Philando Castile shooting in Minnesota. What’s common in these two cases is that the victims failed to fit in the racial group of the police officers.

Facebook has not responded to requests for comment about the picture, shared to celebrate Instagram reaching its 500 million monthly user milestone.

FBI director James Comey has previously said he also covers his laptop's webcam to prevent hackers spying on him.

And digital rights group the Electronic Frontier Foundation (EFF) said it regularly sold its webcam "stickers".
