Richardson, respectively. No witness managed to identify the man they saw hitting Peach. It later transpired that one officer present at the riots shaved off the moustache which he had that day, while Inspector Murray grew a beard and refused to take part in the identity parades. Many of the uniforms that the police wore that day had been dry-cleaned before they were inspected. Cass ran up against misleading stories from the members of Unit 1-1 and in his report he stated "The attitude and untruthfulness of some of the officers involved is a contributory factor." He continued "The action of these officers clearly obstructed the police officers carrying out their duty of investigating this serious matter." Cass decided that he had identified the individual whom he considered most likely to have hit Peach, but that there was "no evidence of a conclusive nature": The officers in that carrier after disembarking, who could have assaulted Clement Blair PEACH were Officer E, Officer H, Officer G, Officer I, Officer J and Officer F, and I give them in that order of possibility. Renton identified these officers as Murray, Bint, Scottow, Richardson, Freestone and White, respectively. Cass's report was accepted by the police as being accurate, and in his 1983 autobiography McNee wrote "when all the evidence was assembled it showed that Blair Peach had died from a blow to his skull. The evidence pointed to the fact that the blow had been struck by a police officer." Coroner's inquest Cass finished the investigation in February 1980; 30 investigators had worked for 31,000 man-hours during his enquiries. He finished his initial report on 12 July 1979, which was sent to the DPP, who, while praising the work he had done, stated that "there was insufficient evidence to justify a prosecution". The inquest reopened a week later. Both Burton and the lawyers representing the Metropolitan Police were given copies of Cass's report, but refused to provide copies to the lawyers representing the Peach family or those representing the Anti-Nazi League. Burton used Cass's report to determine which witnesses to call and which to ignore. Michael Dummett, Wykeham Professor of Logic at Oxford University, examining the case for the National Council for Civil Liberties, observes that as only the coroner and police lawyers had copies of the report, "it was impossible for anyone ... [else] to obtain a complete picture of the evidence". The
