I think measures will be made to keep the game accurate enough without the chores such as paperwork.
Proper discipline and search/arrest methods would probably be nessessary.
Besides, there will be plenty of servers.
Some servers will have 8 year old wanna be cops that do a terrible job and other servers will be hardcore were people don't mind participating in a cop simulator. Arma 3 is a army simulator and it's not all paperwork, look how popular it is.
