Perhaps you missed it, but it has been mentioned. Ordnance lives in Northern Ireland. There the PSNI are all routinely armed, every single one them. On top of which, they are also armed off duty. Likewise, Her Majesty's Prison Service Northern Ireland, UKBA and UKBF, other civil servants within the Northern Ireland Office and civilians due to previous or present occupations are also armed, 24/7.
