They say up to 14 million reports of suspected child sex abuse could be lost each year. I couldn't easily verify that number from the linked NCMEC web site (seems high from the reports I read), but let's assume it's accurate.

However... What can even be done with 14,000,000 annual reports of suspected child sex abuse?

I'm just intrigued to know how that volume of data supports actual investigations, and to what extent it has helped bring perpetrators to justice or helped children suffering abuse.
