In September 2019 Ken Macdonald, the former director of public prosecutions, said the case against Gun was not dropped to stop the Attorney General's advice on the legality of the Iraq War from being revealed. He stated that Gun would not have received a fair trial without the disclosure of information that would have compromised national security. Gavin Hood, the director of "Official Secrets", expressed scepticism about Macdonald's statement and called for the declassification of the official documents referred to by Macdonald.
