Is the policy a step too far? Video game ratings exist to help consumers (especially parents and relatives) decide whether certain media is suitable for them or the person they're buying it for. Children mature at different rates, and so it should arguably be the parent or guardian -- the person that knows them best -- that ultimately decides whether they're ready for adult content. Nevertheless, the headteachers that sent this letter clearly believe that they have a responsibility to report parents whose children have "inappropriate access," or are being negatively affected by mature games. Mary Hennessy Jones, the head who drafted the letter, told The Times it was useful for parents to have "very clear guidelines" about the issue. But in this instance, is such a stance the right approach?
