I have to laugh when I hear the Gardai giving out numbers of cars when trying to track perpetrators of crime.
Anyone can go into any motor factors anywhere and buy a set of plates with any number they want on them. One is not obliged to bring proof of identity, or ownership of the car, or even have the car with you.
The shop is not obliged to ask for any of the above, or to keep records of who purchased what.
Number plates can be stuck on with a special adhesive tape in seconds.
It is far too easy to get new plates.
