If these pictures were of their own daughter's child, and it was the child's father who created the marks (who of course would claim he "only did what was necessary" to impose discipline).... Are they saying they'd be okay with that? Honestly. They would be okay with their grandchild showing near-bleeding welts days AFTER the beating? I say B.S. I say they'd be after that SOB in ten seconds flat.
You nailed it as I was typing my comment. :)
