GR14. Applying a little reality, if you are the owner of an airfield, with somebody causing a serious problem, who had incidentally already beaten up somebody on the airfield badly for questioning what he was doing, you would find it a little difficult to be whiter than white.
So, he called me, being well away from the airfield. CAA enforcement branch (they who do the prosecuting) are mostly ex Met-coppers, with contacts in all the right places to arrange for appropriate investigations and visits, without it being at-all apparent that somebody local (who doesn't particularly want his house burning down) was involved. I've dealt with enforcement branch before, and on one occasion been an expert witness for a CAA prosecution. They do work closely with the police, and as a known quantity to them, I could talk in confidence.
Yes, the ideal in such situations is to go and talk to the local police or customs. But, such things can become a little messy; hardened criminals (and they don't just exist in TV dramas) will beat people up, put burning newspapers through the letterbox, set light to aeroplanes in hangars. To the chap running his airfield, the current problem is a nuisance, some alternatives could ruin him.
For all I know of-course, the local police are monitoring said crook, and simply waiting for him to do something bad enough that they can lock him up for a nice safe 10 years or so. They're hardly going to come back and give me a report are they, maybe it only appears that they're doing nothing. How would I know?
