Surly we all should RP within the server rules, and use faction guidelines to bring continuity to our RP.
Factions make guidelines to improve RP, not rules to control the server.
If an Independent players RP is coursing a problem there are server rules in place to correct the matter, it's not the place of Factions to police the server, that is responsibility of the Admin team.
The in ability of some factions to allow independent player to RP as law enforcement agency both in a military and police sense, means these players are simply moving on after the get wealth trading period to becoming pirates / terrorists.
