The Raincoat Killer: Chasing a Predator in Korea

"The Raincoat Killer", et al, is a documentary on how, despite being one of the most abjectly inept police forces to exist, the Seoul, Korea police caught a serial killer. Apparently, the Seoul police worked on a reward basis for promotion, so they didn't bother themselves with any other crimes but murder; you'd think they'd have been better at it. The documentary is incredulously amusing at times, which is disturbing. It also gave insight into who the P. D. found valuable in society and who they didn't/don't.
