The FBI is to use automated scanners to monitor people’s posts on social networks such as Facebook and Twitter, it has emerged this week – and privacy campaigners have described it as an attack on free speech.
The agency is looking for companies to build it software that will scan social networks for ‘danger’ words – and agents will respond to ‘breaking news, incidents and emerging threats’.
Agents will be able to see people’s tweets on a map – and could use the software to ‘predict’ crimes.
