The Historical Enquiries Team cannot investigate them because European law states investigations into state killings must be fully independent.
As the HET is accountable to the chief constable, it cannot investigate killings by police officers.
A whole week later, it appears that the Historical Enquiries Team do actually report on cases where police officers were involved in killings (see Turgon’s thread on Loughgall, where the RUC’s HMSU took part as well as the SAS).
So, are we to await the reports on the other 49 cases where police officers were involved, or, just the toughening media treatment of the HET (well, their boss, the Chief Constable), the Office of the Police Ombudsman, etc?
Bizarrely, the HET appear to have just issued a report that the Ombudsman’s Office has stated is illegal under EU law?
