Never Bend the Knee
(media.scored.co)
Antifa were attacking random weak individuals like women leaving the march against mass immigration, most of the protesters were non-racist but presumably only Whites (there were all colours at the march but majority White) were attacked, when the National Socialists heard about it they went and beat up Antifa in retaliation and defence of the weak. So morally no crime but legally they started that particular fight.
