SIR – The Batman film (the Dark Knight) is an unrelenting sequence of extreme violence and massive destruction. Rated 12A it is suitable for accompanied children below the age of 12 – and the cinema was packed with them, few being accompanied.

If children are being brought up on this diet I am not a bit surprised at the vandalism, knifings and drive-by shootings current today.

Stemming the tide of violence is in the hands of those in power, not only government, but licensing authorities and film and television companies.

This is not censorship or an attack on freedom of expression but guidance to our way of life.
