Smuggling Soviet psychiatric diagnoses to the West
In 1971 Bukovsky obtained the forensic psychiatric reports on six dissidents, including Pyotr Grigorenko and Natalya Gorbanevskaya. He sent them to Western psychiatrists and asked whether the diagnoses held up medically. The documents helped make the political abuse of Soviet psychiatry an international issue. He was arrested within weeks and sentenced to seven years of prison and camp plus five of exile, and in 1976 the USSR exchanged him for the Chilean communist Luis Corvalán.
