Similar story here except with journalism: I did a course in media law where it was explained that victims of sex crimes always get lifelong anonymity. Journalists must avoid "jigsaw identification", eg giving away details that might identify the victim.

This means in cases of incest it is impossible to report the incest element because it is too easy to identify the victim if you say "x raped his daughter". So it appears in the press as though attacks are random, when actually a shocking number (10% seems conservative) are in the family.

As a sibling comment says, it is chilling.
