Then if they do that post a sanction report for OoRP with the screens of their cargo as proof they were busted.
Personally if i am stopped and the cop has any kind of proof even if he just scanned me and wrote down the amount of cargo i will pay the fine and RP some. Those who do not are OoRP and the Admins will nail them for it just as they would anyone else for being OoRP.
Smugglers are getting lumped all together because of the ones who are not playing for the RP and manipulating the game mechanics to stop them is not fair to those of us who wan't to RP.
