Jailing is done, and VCPD ranks will be done next.
There's barely any code for bank robberies; you can try it, but it won't work after you plant the bomb, so you won't see this for the first few days of beta.
EDIT: VCPD ranks done. SWAT and FBI are included.
Cops will be able to /c rank as well
Updated. Pockets (house storage), loss on death, and gang HQs (per se) have been scripted.
For house storage, you can allow another player access to your house (/c givekey) or take their keys away (/c takekey). You can view what you have stored with /c storage. This will act as a gang HQ system.
That said, you can also give a player guns from your house by using /c give
Lastly, Ammunations will be able to stock and sell civilian-grade kevlars with 65 armour.
