this remember me of a similar issue in Ireland. The media went berserk about a cript under a former catholic orphanage.

A blue-haired sociologist got the records, crunched some numbers, and accused the nuns of neglect and abuse: "they lost 15% of their children and buried them on the spot"

She just did not checked that among poor irish at that time there were 20% child mortality rate. That without considering an orphanage would get mostly the poorest and sickest children.
