I'm not sure about this. The factions usually don't have a leaders (or am I wrong?) and everyone plays on own. I'm sure some restrictions might help, so If we are in same faction we couldn't destroy vehicle. ?
I don't know how server works, I just joined and probably wrote something wrong here. :p
I don't think it's needed honestly. If there's any officer who shooting randomly (this is against our server rules) you may go ahead report him to online admin in-game or by submitting a report on forums
First, it can be abused and I dont think this would help in anything.
Secondly, we have staff to handle deathmatch and such a thing.
Thirdly, if a cop kills a player, he will get demoted automatically by the system.
As pointed out by Mega there is already a system to demote or dismiss cops for killing innocent and yellow players and cops.
I will however extend this to repeated attacking.
I recently added a new 'public service offence' system. When a player is a public service role (cop, medic or firefighter) commits a crime they will be automatically warned/demoted/dismissed and finally temporarily banned from having a public service job.
I just need to add detection for repeatedly attacking other players which you shouldn't be attacking.
Need a system to detect self-defence however. Whoever damaged first is the attacker, if that attacker fights back it is counted as self defence as is not an offence.
