This chapter focuses on the civil liberties, legislation, and activities of the Finnish State Police during the Second World War, when Finland waged two wars against the Soviet Union. The first was the Winter War, which took place between November 1939 and March 1940. The second took place after the interwar year of 1940–1941, when the Continuation War erupted, lasting from June 1941 until September 1944. The Soviet Union had increased its intelligence gathering in Finland, especially in Finnish Lapland. The chapter explores what happens when national security clashes with civil rights and liberties. It examines the activities of the State Police through six Members of Parliament who represented the opposition and were against the war. The six social democratic MPs were filer Mikko Ampuja, principal Vaino Meltti, journalist and author Kaisu-Mirjam Rydberg, journalist Yrjo Raisanen, dentist Cay Sundstrom, and journalist and previous Social Democratic Party secretary Karl Harald Wiik.
