In 2003, a Hokkaido cop named Yoshiaki Inaba was sentenced to nine years in jail, on charges including drug use and possession with intent to supply. During his trial, the former police inspector revealed that his impressive career record had involved an unhealthy degree of collusion with contacts in the criminal underworld. Prior to his arrest, he'd been selling stimulants in order to purchase illegal firearms that he then turned in to the police department — and, he claimed, doing so with official approval.
