While it is interesting to discover that things we deem obscene are permitted, and sometimes occur, and that the occurrence of something as severe as a ten year old marrying their rapist is non-zero, it is very dishonest to discuss these things without statistics.
These articles often start with specifics of the most obscene cases, then should they ever get to frequencies, conflate many not-as-severe or irrelevant cases, to bolster the appearance of severity. E.g. a statistic might include marriages where either party is under 18 years.
