An anonymous reader writes: An MIT student was arrested today at Logan Airport because she "had a computer circuit board and wiring in plain view over a black hooded sweat shirt she was wearing" when talking to a staffer at an information booth. She was visiting the airport to greet an arriving friend. She was wearing the shirt at a Career Fair earlier to stand out, and apparently didn't change before entering the airport. The police believed the object was a bomb and she was surrounded by a group of officers with submachine guns. Didn't the city learn its lesson from the Aqua Teen Hunger Scare?
