Another was the longtime editor of the communist newspaper Friheten ("Freedom"), Arne Jørgensen [1], who told me about how he for a period regularly had agents of the security services stop him in the streets to rattle him by e.g. commenting on details of private conversations he had the previous day with his wife at home.
This was reported regularly for years, but was laughed off as conspiracy theories, until it got a point where it could not be denied any more, and the Lund report[2] revealed extensive illegal surveillance.
Former prime minister Willoch defended the illegal surveillance against e.g. AKP-ML (Maoists ) with arguing they were an illegal organization. But no decision to outlaw them have ever been made.
During the writing of the Lund report, it became clear that one of the members, Berge Furre [3], a theologian and former Socialist Left (SV) politician, was still under illegal surveillance during his work on the report into the illegal surveillance.
None of the people involved were charged with anything. The security services changed name from POT to PST, and everything else remained largely unchanged.
Years later, when the first reports of Norwegian complicity in NSA surveillance was reported, the paper that reported it was pushed into a retraction after Grandhagen, the then leader of the notoriously tight-lipped military sercurity service uncharacteristically "took the blame" for reported surveillance that for every other country in the same document had turned out to be civilian surveillance of their own citizens, and claimed that Norway was somehow feeding the NSA metadata on phone conversations in Afghanistan of a volume that meant Norway somehow must be tapping every phoneline in the country.
Nobody in the press admitted to asking follow up questions about why military intelligence would suddenly gie out details like that, nor about why the US would be interested given reports that the US at the time themselves did not just capture meta data, but full voice recordings from Afghanistan.
Nobody reacted. Both Dagbladet and Aftenposten (major newspapers) deleted a slew of comments in their forums asking why nobody had asked questions about this of Grandhagen.
Like with the surveillance uncovered by the Lund report, any questions about this now gets met just with a shrug.
Then a couple of years ago, Aftenposten reported about a lot of unregistered IMSI catchers in Oslo. Again the intelligence services just insisted they were looking into it, after which the IMSI catchers "disappeared".
There's decades of history of this bullshit in Norway, and decades of experience showing that most people just refuse to question the official stories until things like the Lund report, and then go back to quietly accepting the official stories.
Part of it is probably that it has been relatively benign in Norway. No secret prisons, very little government interference in the press, etc. - it's mostly been just surveillance, so few people have been affected, and those who have been affected have been far out on the political fringes.
But I see no reason why that would change now.
