the Latvian Legions did not participate in this. The Arajs Kommando were not latvian legions
Whether or not the Latvian Legion was involved in war crimes is a matter of controversy. However, of note, particular to the Latvian Legion in Latvia, the last mass killing of Jews, gypsies, or people caught up in Nazi Germany's program of systematic genocide occurred in March 1942, a year before the formation of the Latvian Legion and was carried out by specially directed German SS units. The Latvian Legion was fighting for its freedom, swearing to fight against Bolshevism and the return of the communist regime into Latvia. Their concerns were far different from Hitler's national-social ideology. Latvian historians maintain that the Latvian Legion itself was a front line combat unit and did not participate in any war crimes. Moreover, the Latvian Legion, being an organization of conscripts, was exempt from the opinion rendered at Nuremberg trials,[5] consistent with findings by post-war Allied authorities. Nor has any Latvian ever been accused of any war crime while a member of the Latvian Legion.
However, as earlier members of the Latvian fascist movement Pērkonkrusts[26] and Holocaust participants such some 600 members of Arajs Kommando[27] later made it into the Legion,[8] the presence of these individuals as well as allegations against police battalions subsequent to the formation of the Legion[28] have been used by Soviet and later Russian authorities to denounce the entire Legion as war criminals
