In the Hillsboro' cover up, not all the police officers on duty at the stadium on 15 April 1989 knew about the witness statements of many police witness statements had been re-written, or edited and composite versions of statements had been created in some police officers names without the knowlege or consent of those individual officers! The police officers responsible for this criminal activity had the knowlege of what they had done, but the named officers whose statements were 'doctored' had no such knowledge! Some cops got innocently caught up in a conspiracy run by a handful of bent coppers and a dodgy senior Crown Prosecution manager!
Same type of corruption, different case, Bamber case and Hillsboro cover up!
