Government ad running on British radio station tells public to report people who close their curtains as potential suicide bombers.

The advertisement, produced in conjunction with national radio outlet TallkSport, promotes the “anti-terrorist hotline” and encourages people to report individuals who don’t talk to their neighbors much, people who like to keep themselves to themselves, people who close their curtains, and people who don’t use credit cards.
