Every year for two days in August, the picturesque medieval town of Shrewsbury, Shropshire holds a flower show. In fact, the 150-year-old Shrewsbury Flower Show is believed to be the largest and longest-running flower show not just in Britain, but also the world. It attracts over 25,000 visitors, who enjoy arts and crafts, military bands, show jumping, a firework display, demonstrations by celebrity chefs and, of course, meticulously designed flower and plant displays. To most people, this probably sounds like a wholesome family day out. But to the British state, Shrewsbury Flower Show poses a deadly security risk.
