The CAA have done nothing to me personally but the flying mags have, in the past, been full of tales of pilots being prosecuted for the most petty of incidents like low flying. I remeber one PA28 jockey being done for speeding on the taxiway and fined.
PPLs need an organisation that maintains an arms length distance from the regulators, not a cosy, old boy's network the matter raised in this thread appears to suggest.
