There were many mistakes including Mannerheim as the Chief of staff, Soviet POWs in concentration camps and mention that only a few Finns were punished on war crimes after the war. The last one is not true, because about 300 Finnish sentries were sentenced for the killing of Soviet POWs alone after the war, not to talk about other cases. All accusations were investigated and if there were proves those involved in these crimes were sentenced.
The case of Arno Anthoni, Chief of State Police (Valpo) between 1.2.1941 - 29.2.1944, is different because he was released and even paid compensation after a rather odd "trial". It later appeared that the jugde knew Anthoni well: they both had been in the Finland - German Friendship Associasion.
Unlike claimed in the above text exchanging of POWs which it actually was is not a war crime (or was not in the 1940's). Finland received Finns, Estonians, Karelians and Ingrians in turn. Most captured Soviet Jews introduced themselves as Russians and they lived among Great-Russians (like Russians were called in Finland). It is likely Finns didn't even know who were actually Russians or for example Jews unless the POWs self told about it.
There is no need for any "truth commission" in Finland because all records are public and available for researchers. This is basically nothing totally new. The debate has mostly concerned about some numbers which have in some cases been estimates. The number of Jewish refugees in Finland was for example actually slightly bigger than was known.
About the case of the eight deported Jews Valpo handed over now seems (sources: Robert Alftan and Hannu Rautkallio) that Germans asked initially only for a one person (Dr.?) Walter Cohen (in some papers Kohen), who in fact was known on having a more or less criminal background. He although had so good "friends" and contacts in Finland that he could avoid yelding to Germans. Instead to satisfy Germans the Chief of State Police Arno Anthoni (most likely without authority) offered these eight poors who then were given to German hands before Anthoni's superiors noticed what was going on. The result we all know. The deported ones belonged to a small group of Jewish refugees who were in work service in Finland since late 1941 and were transported from a construction site to another until were moved to Suursaari island for fortification duties.

It is interesting that when Heinrich Himmler visited in Finland in the summer 1942 Finnish "Secret Service" could photograph the content of his briefcase which included the full list of all Jews living in Finland. It is told (but never confirmed) that Arno Anthoni had delivered that list to Germans when he had earlier visited in Germany. Anyway that was a clear message to the Finnish authorities on what was going on. Finns rejected all Himmler's proposals of deportations of Finnish Jews by telling that "there is no Jew problem in Finland".
