Generally speaking, I think Gardai make very innconsiderate neighbours. They have Harcourt Street (and the nearby Harcourt terrace) destroyed with careless, thoughtless and in some cases dangerous parking. They regularly block wheelchair access ramps, park on footpaths and regard coach parking bays as their own.
Thes excuse is often made that they need the cars for official purposes but this doesn't hold water. I often see one such car in Harcourt Street that has a child seat in the back. I don't see how this could be used for official purposes (unless it's part of some sort of preventive strategy).
