The guy is still alive and could perhaps sue for libel if they used his full name. An earlier Swedish movie about Olof Palme was probably libelous, but got away with it since his name was never used.
Sweden must have an exceptionally strange libel standard then, given that the series is explicitly about him: "This is the unbelievable story of Clark Olofsson, the controversial criminal who inspired the term "Stockholm syndrome." Based on his truths and lies.".
Sweden, is .. a strange country. Yes, its liberal. But at the same time. Its part of the old world, as in the ancient world, that was before the WorldWars. It had eugenics until the 2000s.
What do you have in mind with “… until the 2000s”?
According to Wikipedia:
“ Compulsory sterilisation in Sweden were sterilisations which were carried out in Sweden, without a valid consent of the subject, during the years 1906–1975 on eugenic, medical and social grounds.”
So the main sterilization program ended 1975. However:
“Between 1972 and 2013, sterilisation was also a condition for gender reassignment surgery.”
