China

Taiwanese businessman Morrison Lee spent almost four years locked up or under an exit ban in China, detained only because he had postcards deemed sensitive and a few publicly-taken shots of military vehicles on his phone.

Lee is one of many overseas victims of China’s secret RSDL jail system. Under what is called 'Residential Surveillance at a Designated Location', police can hold victims incommunicado without sunlight, exercise, or access to a lawyer for six months. Well-known RSDL victims include the Canadian Michaels (Kovrig and Spavor), Australian journalist Cheng Lei, and countless Chinese human rights lawyers.
