Military Intelligence Bureau of the Ministry of National Defense is the successor of the controversial Bureau of Investigation and Statistics of the National Military Council of Republic of China in the early ROC era and during the Second Sino-Japanese War. It was nicknamed "Jun-Tong" (軍統), literally Military-Statistics. Before 1949, many high-ranking police officers were trained by the Military-Statistics. After 1949, many of them, and a lot of intelligence officers from the military intelligence agencies, were flooded into Taiwan police organizations. The typical case is Wang Lu-chiao (王魯翹), Father of Wang Cho-chiun, the Director-General of National Police Agency after 1 June 2008. Wang Lu-chiao was an intelligence officer of Military-Statistics and sent to Hanoi to assassinate Wang Jingwei between January and March 1939 without success. Wang Lu-chiao, after 1949 and until his death by a vehicular accident in 1973, became a successful criminal detective and later served as the Police Commissioner of Taipei City Police Department in the 1970s.
