It still goes on as well. At home two years ago a taxidriver told me what happened to a pal of his when he was called to pick up a Garda sergeant from a pub. The Sergeant was drunk and in no fit state and belligerent with it- tried to demand a 'garda discount' when being dropped off where his 4x4 car was. The Garda ended up throwing the right money into the taxidriver's face and climbed out of the tax and into his 4x4 and drive off well drunk up the road.
The taxidriver in a fit of anger foolishly rang the Garda station nearest him and reported a drunk driver in a 4x4 and gave the license plate over the 'phone. Didn't hear any more until he got a letter saying his taxi license was withdrawn as he was 'not regarded as a fit and proper person'.
So thats how that goes. A man lost his livelihood because of a drunk thug with Garda ID.
