I propose that a Witness Protection Program be introduced.
Yes, I know this is MafiaRP not PoliceRP, but upon re-watching some older mafia movies I saw an interesting trend that I think would also be fun in the server. People that escaped the mob, went into witness protection, but then get found out and now have to scramble after feeling like they got away from it all.
Now, how would this work? Members of criminal factions can come to the police and, given proper reason or information (IE if they can ICly confirm they are going to be killed, they are trying to leave the faction, etc), then a high-ranking member of the police force or a detective can place them in witness protection. This would include removing them from their current faction, giving them a free name change (government subsidized), and if possible a change to unique identifiers like their SSN. Due to the amount of processing this would take, having this be restricted to only very good information or restricted to the very high ranking members of the PD would probably be best.
