Would love to see it and was thinking this when i got locked up in the LS county jail map, that could definitely be used for low level crimes(evading, graffiti etc) with jail time allowed between like 1 and 10 minutes, Alcatraz could be for our (attempted)murderers, mass murderers, kidnappers etc with jail times between 10mins and 30 mins.
To keep roleplay active there could be reward incentives for the DoC officers for instance we could make it if the DoC's not paused, in the jail and have written a /me cmd when an inmate is doing their time, on completion of their time the DoC could get a reward of $1k or smth from the state for "prison duties"
Could even make a reward so that criminals will want to do the jail RP even more by removing the notoriety cost to a /gu'd suspect
