Kaohsiung Incident
Although officially a military division, Taiwan Garrison Command actually functioned as a secret police organization. It was actively involved in suppression of suspected Communist sympathizers or Taiwan Independence activists. Many pro-democracy activists were imprisoned as well. Famous cases include the arrest of Peng Ming-min, the Taiyuan Incident, and the Kaohsiung Incident. Also, it was rumored to have been involved in many politically motivated assassinations/murders, such as the murder of Lin Yi-hsiung's family and the murder of Dr. Chen Wen-chen.
