Chris Thornton on the Billy Wright Inquiry, notes that it is not the gaps in ten year old Police files that raise suspicions of state collusion in the killing, but that those gaps are replicated in exactly the same places across supposedly independent agencies:
Gaps in the files can be covered by material from another department, indeed some familiar with the material available to the inquiry say that has already been the case. But some gaps remain notable. Some of the missing Prison Service material should have been duplicated in the police file on the murder investigation. But it appears the police file may have the same gaps.
