I wonder if , by any chance was it the roads policing unit ( traffic corps) that were operating the roadside checkpoint. If it were then why aren’t you praising the particular Garda unit for doing the job that they are supposed to do, it’s like the guy who gets caught at 80 in a50 zone , “ ah sure I was only a little bit over the limit, why aren’t you catching someone else for something and let me off”.
Trying to make a bit of a point that there’s different units in the Garda, so why do you complain when you see a particular unit doing the job their tasked to do.
