He also apologised to the families of both PC Miles and Bentley for his actions, as well as his own family for the press intrusion they had suffered over the years. Though Bentley had never been accused of attacking any of the police officers, who were shot at by Craig, for him to be convicted of murder as an accessory in a joint enterprise it was necessary for the prosecution to prove that he knew that Craig had a deadly weapon when they began the break-in. The Lord Chief Justice, Lord Bingham of Cornhill, ruled that Lord Goddard had not made it clear to the jury that the prosecution was required to have proved Bentley had known that Craig was armed. He further ruled that Lord Goddard had failed to raise the question of Bentley's withdrawal from their joint enterprise. This would require the prosecution to prove the absence of any attempt by Bentley to signal to Craig that he wanted Craig to surrender his weapons to the police. Lord Bingham ruled that Bentley's trial had been unfair because the judge had misdirected the jury and, in his summing-up, had put unfair pressure on the jury to convict. It is possible that Lord Goddard may have been under pressure while summing up since much of the evidence was not directly relevant to Bentley's defence. Lord Bingham did not rule that Bentley was innocent, merely that there had been fundamental defects in the trial process. Another factor in the posthumous defence was that a "confession" recorded by Bentley, which was claimed by the prosecution to be a "verbatim record of dictated monologue", was shown by forensic linguistics methods to have been largely edited by policemen. Linguist Malcolm Coulthard showed that certain patterns, such as the frequency of the word "then" and the grammatical use of "then" after the grammatical subject ("I then" rather than "then I"), were not consistent with Bentley's use of language (his idiolect), as evidenced in court testimony. These patterns fit better the recorded testimony of the policemen involved. This is one of the earliest uses of forensic linguistics on record. In a case with similarities to the Bentley case, a House of Lords judgment of 17 July 1997 cleared Philip English of murdering Sergeant Bill Forth in March 1993, the reasons being given by Lord Hutton. English had been handcuffed before his companion Paul Weddle killed Sgt
