it may sometimes seem that the authorities work "too" slow, but some times their hands are tied, especially after anonymous reports. But also after non-anonymous ones.... the authorities need HARD FACTS in order to do something, not just "rumours". Yes, they will check into stuff as far as they can, but data protection laws even prevent authorities from investigating into stuff. Often the CAA or whoever is working behind the scenes which WE, on the outisde, do not see!
example: the authority receives a report on a pilot that supposedly has epilepsy yet keeps getting a medical because he is friends with the doctor. So, on that information, what can the CAA do? Ask the doc how thoroughly he checked this guy? Insist the doc provide confident information and thus incriminate himself perhaps?
It turned out, the pilot did NOT have epilepsy! The report was wrong.
Once I heard rumours (this is over 15 yrs ago and no internet back then) of a pilot who lost his medical for power gliders, but he continued to fly ultralights since the requirements were "easier". What to do? The whole club knew about it and continued to let him fly their ul. Who am I to pass on the rumours, not knowing 100% if they were true? Confront the pilot and tell him what people are saying and gets all upset with his friends for spreading (possible) false rumours?
It's a very tough situation. But as I said on the removed thread... just let people know that there is a possibly critical "situation" with a certain person and if anyone wants further information to pm the thread opener. That way it all stays private and only those involved get further information.
