BoeingEurope;
The UK CAA have a very active legal/enforcement dept mainly staffed by ex-coppers.
I fell foul of them some years ago, and despite great mitigation offered by my employer and a passenger I decided to accept a caution rather than fight through the courts with threats of huge costs from the CAA.
That caution will remain on my CAA record for the rest of my flying life.
When the CAA man came to issue my caution and for me to sign the rather imposing certificate all the pilots in the company formed a guard of honour and escorted me to the desk.
The CAA man saw the funny side of that, but believe me you NEVER want to be interviewed by them, if you are take a bloody good lawyer.
