Firecracker Last June two teenagers let off a big firecracker (which measures 5,9 x 2 inches) at the playground, near children who are 5 years old. I was in my office when the firecracker exploded, the walls were shaking. My immediate reaction was to bend down. I decided to demarcate a secure area and call the police. I took the initiative to view security cameras. Next day the headquarter complained to the gendarmerie. Children had trouble to get over, many of them had a nightmare. I hope that the police will catch up with and make an arrest them.
