“Matthäus happened upon this revelation in part due to a stroke of luck, when, after word of the massacre’s real whereabouts, date and unit circulated in German media last year, a reader came forward with some vital information.
Based on correspondence from the time in his family’s possession, he said that the shooter bore a striking resemblance to his wife’s uncle, Onnen, and provided the aforementioned biographical details.
The pics were then sent to open-source journalism group Bellingcat volunteers, who were able to forensically analyze it using AI.”
'AI', as we are all discovering as we use it, is very prone to giving you the answer you are seeking. Without seeing the full spectrum of research and the methods used this is not verifiable at all. And if Gen AI was used at all to enhance the imagery or 'imagine' how the guy looked as SS...forget it. If they got this tip and then 'guided' AI into verifying the claim, this is suspect at best.
We should think long and hard before condemning a man and his family name for something he may not have been guilty of.
