Last year, New Scientist revealed that the US Department of Homeland Security is developing a system designed to detect “hostile thoughts” in people walking through border posts, airports and public places. The DHS says recent tests prove it works.
Project Hostile Intent as it was called aimed to help security staff choose who to pull over for a gently probing interview – or more.
