I don't mind playing both roles, I mean that keeps the game fun, but I'm not sure if that should be on the same server imho.
I've seen the powers massively shifted to one gang, where 4 of them are cops and 6 of them are Civs. After a restart the roles are reversed.
Personally I kinda find that unfair especially towards small crews, which can not gather money by playing the cop side.
Why not change over to a different server? For example be a cop on server 1, a rebel on server 2. It's kinda weird to have a gunfight with somebody, who is a rebel, and after the restart he is arresting you for speeding.
Just my feelings, don't wanna hurt anybodies feelings
