When I was in Ireland the Guardia didn't have guns; did that change, or are there just armed units?
Also the Guardia not having guns was apparently one of the reasons they are a joke and completely unable to regulate the drunk crowd at night.
The Gardai still don't have guns, but they're the Republic of Ireland police force... The armed ones are the
Northern Ireland (seperate from the Republic) cops, who apparantly sport a Glock 17 on all patrols, as well as occasionally carrying rifles, carbines, and extendable batons. And given Northern Ireland's history when it comes to what constitutes justifiable force (
http://en.wikipedia.org/wiki/Bloody_Sunday_(1972)), well, you kinda have to wonder about the advisability of giving their police force the ability to shoot any kids they deem sufficently suspicious-looking.
And maybe the Gardai not having guns does make them inefficent, but to be honest I'd rather have inefficent police than actively homicidal police.
