All Government jobs require the members to stay clean, they all have limitations on breaking the law. I am the owner of Los Santos Customs if one of my members breaks the law for example robbing someone, and it is caught on camera and reported to us they are fired. MD, PD, DCC, Weazel are all the exact same way, if they are caught they are fired depending on the charge. At LSC if someone is charged with brandishing a firearm which seems to be a normal thing now cause we use them to defend LSC and the cops arrest us pretty much no matter what that is looked over simply cause I know they are defending people and property at LSC. Even if the gangs banded together and said don't rob postal trucks there are many solo criminals that have small groups that have no reason to not rob you it would be a never ending thing they are criminals so they are going to rob you. I do agree however if there were more things for criminals to do that would draw their attention away from robing people that just simply are not provoking the rob it would be good and the development/staff team is working on things on a daily basis to improve such RP.
