Much depends on context and treatment. The Board has a strict policy, for example, on sexual violence, especially material which exploits or glamorises rape or sexual assault. Research suggests that a minority of men can be influenced by violence, particularly sexual, towards women, and for this reason the Board ensures that such images are not permitted for purposes of 'entertainment'. The Board is careful to ensure that emphasis on the process of violence and sadism is limited, so that scenes of torture or violence are not presented as enticing spectacles. It is also the responsibility of the Board to avoid classifying works, including sexually explicit works, which infringe the criminal law, including the Obscene Publications Act 1959, the Cinematograph Films [Animals] Act 1937, the Protection of Children Act 1978, and the law of blasphemy. The Board may also cut detailed depiction of imitable dangerous or criminal techniques, such as how to break into cars or make explosive devices, and the glamorisation of weapons. Film distributors sometimes make cuts to films before they are submitted to the Board, in order to gain a lower classification with a view to increasing the audience.
