In dozens of prosecutions each year, parents or caregivers are charged after infants who died under their care have been found to display supposedly infallible indicators of abuse — in particular, subdural and retinal hemorrhage with brain swelling. Many convicted defendants stoutly maintain their innocence all along; others are sent to prison on the basis of equivocal “confessions”. Even when (as is common) there is no pattern of previous child abuse, it often happens that authorities remove other children from an alleged abuser’s home as legal action proceeds.
