A LAJ copilot was arrested because he drank too much and hit a police officer in Kanazawa. He and other pilot had been drinking together. He was supporst to board a JAL plane next morning, but he couldn't. He had been in a police office, so the flight was canceled.
He mustn't drink alcohol before flight in 12 hours. He broke the regulation. It was too dangerous. Airline companies have to keep safe operation. They have to supervise pilots strictly.
