Its a very simple idea.
Introduce a new police spawn at all the PD's and one for the Jail. Call the ones at the PD 'Police Constable' and the ones at the jail 'Police Warden Constable'
The difference between a constable and a trainee is that the constable has access to the police radio and their own set of cars at the PD's.
To be a police constable you must have 200 hours in game and must make an application to the SAPD which will be required to be accepted to gain access to the spawn. This gives the SAPD more to do as they don't do much at the moment, lets be honest.
The application process should not be difficult like for the PC qualification but the application is to show that you want to be serious and have access to a police spawn so you can efficiently use the police radio.
This then also prevents noobs and trolls from having access to the police radio as they can only use the trainee position unless they have the minimum hours and have applied and been accepted.
Also for older players who do not have the minimum hour count on the scoreboard ingame because it never existed when they played the most, should still be allowed access to the job even if they do not physically have 200 hours recorded on the new scoreboard thing. This would include people like me and others older players.
This job should be allowed for everyone, criminals, civilian (oops rip ALT) and cops obviously.
