"The Sunday Times" attempted to undermine the programme's credibility with its own investigative journalism. Citing "official sources", the paper told its readers that "This Week"s account of the shootings was "crucially flawed", and "bore no resemblance to what happened". It went on to claim that several of the programme's witnesses felt that "Death on the Rock" had misrepresented their statements. It stated that the documentary's technical advisor, Lieutenant Colonel George Styles, was aggrieved that two of his "key opinions" had been omitted from the version broadcast—specifically that what Proetta interpreted as a gesture of surrender may have been an involuntary reaction to the bullets striking the suspects' bodies, and that the IRA members could still have detonated a bomb in another vehicle parked on the Spanish side of the border. The latter opinion was omitted because the "This Week" team saw little for the IRA to gain by detonating a bomb on Spanish soil, while the former was included in the broadcast. Josie Celecia, it alleged, had dismissed Proetta's account as "ridiculous", while Stephen Bullock had contradicted Proetta's statement that she had seen plain-clothed soldiers arriving in a police car—testimony "The Sunday Times" believed "destroyed" Proetta's evidence. Both witnesses complained in letters to other newspapers. Through these, it emerged that Bullock had dismissed only one detail in Proetta's evidence as "ridiculous", while he and Proetta had been referring to two distinct police cars in their statements. "The Sunday Times" omitted Styles' belief that the shootings were a pre-emptive attack. Styles' view was one of "two active service units waging war [...] taking IRA members out quickly, cleanly, and without other people being hurt—that seems to be the only way". Several newspapers were critical of the IBA's decision to allow the documentary to be broadcast.
