“In particular, people who receive such material involuntarily — for example in the context of a WhatsApp parents’ group — risk a minimum sentence of one year,” Buschmann said in a statement. The same, he added, also applies “in the case of teachers who have discovered child pornographic material on students’ cellphones and have forwarded it to alert the affected parents.”

So seems less like they have an excess of CP and more like they have a poorly worded law that allows prosecution of people who aren't the actual problem. Though teachers forwarding it to parents is a bit weird
