I believe a good addition to the prison system would be a Prison Break system. The way it could work is be connected to commissary items.
My idea for this system would be as follow. Please feel free to add-on to this because it's not a funny thought out idea.
Player gets arrested and is arrested for x hours lets say 6 for the example.
After the player roleplays for around 3 of those 6 hours purchasing commissary items the player can initiate a prison break(How? TBD)
Obviously it should be regulated and require a group of criminals to start. It can only happen an allotted amount of times a day as well.
The risk -
Wanted by the SFPD if you escape. There will be an APB for you until your unserved time is finished.(In this case 3 hours until the APB is gone)
Extended sentence(Half of the unserved sentence added on) So in this example they had 3 hours left they would now have 4.5 if they are caught.
Reward-
You escaped prison and didn't have to serve the last few hours.
Update -
Based on people opinion
Instead of having the remaining time added as an APB the APB becomes permanent until the player is killed or arrested by the police. (Andrew Bones, Asixl)
Longer sentence if caught. (Highwire)
Occurence change to 1 time a week (Dalek)
Discuss if you like.
