Could be wrong, but the police "incompetence" in stopping the getaway of the robbers ( apparently it was 2 hours before they responded) points more towards a loyalist operation,given the links between the police and loyalist groups.

An excellent wheeze to completely derail the peace process.

Just goes to show what a morass N Ireland still is, while we try to teach the world how to practice "democracy".

Maybe the yanks will need to come in, raise Derry to the ground and install a puppet government...Ake
