It’s hard to read the reports emerging from Bucha and other Kyiv suburbs, and nearly impossible to look at the images. Retreating Russian soldiers have left evidence of unthinkable brutality. Ordinary men and women lie dead on the street, in the dark mud and dirt, many shot, some with hands tied behind their back. People were found still clutching shopping bags, one splayed next to a tangled bicycle. There are mass graves, and there’s evidence of torture. Ukrainian authorities say the bodies of 410 civilians have been recovered from towns around the capital.
