Good point Prysin!! DEATH TO FARMERS!
However, with the influence they have in the council of the rising sun (The council of people in charge of passing laws), it's doubtful that anything will be done to prevent Farmers from flying.
Piracy is not allowed, to anyone, if the Farmers are committing piracy in front of a KSP or KNF, and those officers don't do anything to stop them, I suggest you to take screen shots, and make a complaint to the KNF High Command about it.
We all know that Farmers and Hogosha do pirate in kusari, but the majority of them are smart enough to don't do it in front of authorities, some few indies who thought they were unpunishable did it, and they ended dead by KNF (there are at least 3 cases I remember). Unfourtanely, as I said above, both groups have weight in the council, and furthermore, they were never accussed with good evidence (except by Kempetei... heh) that they committed piracy.
The KNF needs people reporting illegal movements from Farmers and Hogosha, but no one really does it.
EDITED: I agree with Dab, putting that into the Legal Codex will show that we care about Rheinland's problems.
