The FBI says they have arrested a man on terrorism charges for trying to blow up the New York Federal Reserve bank in Lower Manhattan's financial district. It was a joint operation with NYPD and they say the suspect was flagged after he made suspicious posts on the Internet. It turns out, however, that the FBI provided the Bangladeshi national who came to US earlier this year with the fake explosives he attempted to detonate. So why is it called a terrorist attack then?
