At least 71 bombs have exploded in Bangkok this year, both before and after the failed Red Shirt revolution of April and May, causing random damage, injuries and a handful of deaths and an increasingly worried and frustrated citizenry. During September, successful and failed bombings have targeted a school, a shopping mall's car park, the Public Health Ministry's parking lot, the Royal Turf Club, a ruling politician's office, and public sidewalks. The scattered timing and locations of the blasts have people baffled.
