Facebook's encryption plans could help child abusers escape justice, NCA warns

Police and a children's charity have warned that a man who admitted 96 counts of child sexual abuse could have escaped justice if technology giants had already toughened their encryption.

David Wilson targeted young boys aged from four to 14, getting them to send compromising pictures and video. Some were so traumatised that they considered ending their lives.
