Dork or no dork, in Belgium, after approval from the authorities for flying in- or over a city, the pilot must be clearly recognizable. That are the rules whenever you like them or not.
On other boards (like InspirePilots) there is a lot of complains about idiot pilots posting idiot movies on JoeTjoep. And that is true imho.
If you have a license, you stick to the rules. I have a license and I stick to the rules.
So, if a police officer stops me while in filming, bad for him and JoeTjoep because no movie where I got arrested.
