An excellent analysis, as usual from Ed Moloney. The Police Ombudsman is unable to investigate not only MI5 but any other British state organ, such as the Army. Another issue is raised by this. The police have a duty to uphold the law and preserve life and property. No such obligations exist in the other agencies. Where does that leave justice?
