the board viewed the film on 17 may, a little over two weeks before the planned broadcast. in the event however, they stipulated only that the film be preceded by a caption to say that it was a drama-documentary; and that some adjustment be made to the wording of a final caption noting the statement to parliament by the attorney general sir patrick mayhew in january 1988, that although there was evidence of ruc officers obstructing and perverting the course of justice, he had advised the director of public prosecutions for northern ireland that due to considerations of national security a prosecution of those officers would not be in the public interest. subject to those two provisos, the board cleared the programme for transmission.
