Northern Ireland Troubles (Legacy and Reconciliation) Bill

Sinn Féin has always argued that, because in the early years of the troubles fatal shootings by armed forces personnel were investigated by the Royal Military Police, and only after a few years was that transferred to the RUC, those investigations were not article 2 compliant. As the Government have deliberately strengthened the role of article 2, via their own amendments, does that mean in practice that every single fatality prior to 1972 is likely to be reinvestigated in order to be article 2 compliant?
