The offbeat and in parts grizzly Shanghai Museum of Public Security (上海公安博物馆, Shànghǎi Gōng’ān Bówùguǎn; 518 South Ruijin Rd, 瑞金南路518号) offers three floors of exhibitions detailing how the Chinese authorities keep control. Displays depict how authorities have cracked down on criminals and illegal dealings, from drugs to gambling and everything in between. Visitors can view police equipment, including weapons, throughout the ages, there are bags of seized drugs, plus restraining equipment (from stock and shackles to tasers and handcuffs). Displays cover how hangings were carried out decades ago, and the modern methods used today to help police activities, including drone and street surveillance. Car aficionados will enjoy the original police vehicles from the mid-20th century. Passports are required for entry. At the time of research, the museum was closed for renovations but due to be reopened.
