The BBC Roadblock Film, 1979
In October 1979 a BBC Panorama crew filmed armed, masked IRA members manning a roadblock on the roads around Carrickmore. The film was not broadcast - instead it became the subject of a parliamentary crisis. The Conservative MP Tim Eggar asked Margaret Thatcher in the Commons to "express extreme concern" that the Panorama team had "encouraged the IRA to break the law". The Ulster Unionist leader James Molyneaux called the filming "at least a treasonable activity". The BBC governors issued a statement acknowledging the filming "would appear to be a clear breach of standing instructions in relation to filming in Ireland". Police seized the footage under the Prevention of Terrorism Act in 1980, following a further outcry in parliament and the press. The film has never been shown in full on British television. The incident became one of the defining moments in the long argument between the Thatcher government and the BBC over coverage of the Troubles - the same argument that would later produce Thatcher's 'oxygen of publicity' doctrine and the broadcasting ban on republican spokespeople.
