It wasn't that long after the Baugnez crossroads incident during the Battle of the Bulge . War is a horrible thing . Total war like WW2 is even worse . Don't forget , by this stage of the war , very few allied airmen were reaching POW camps , whether they fell in the target area or not , and any German man of military age not wearing a uniform and pointing his weapon in the direction of the advancing enemy was likely to be shot or hanged by flying courts martials of SS men , and concentration camp victims elsewhere were still being executed by the thousands . People like Canaris were only shot in the last week of the war . By the end of the war , everyone was firing at the SS , Germans and Allies alike .and again the problem is, it makes you worse than them.
They deserved to die, but, summarily, to my mind even then, it shouldn't happen.
They (the Americans) should have been court marshaled for that act and been jailed.
There is no excuse, more so their officers.
Frankly , there is every excuse , by prolonging the war , Nazi fanatics ensured the deaths of tens of thousands , so they deserved what they got .
