In recent months. the Soviets have cleansed Moscow of dissident elements to make sure that these people do not come in contact with visitors from the West during the Olympic games. Evidence of the worsening situation is not only reflected in terms of numbers. but also by the intensification of persecution toward potential emigres. One case. the Vallery Raines family of Riga. U.S.S.R.. applied for an exit visa in August 1978. Not only were they denied in December 1978. but Vallerys wife Galina was brutally murdered on February 5 of the following year. Her family and friends believe this was done by the Government to intimidate other Jews in the community who wish to leave the Soviet Union.
