Prisoner rehabilitation

The state could have a program where prisoners could opt to be rehabilitated by the lab. they could be trained by you to be productive (or submissive) members of society, they could have a danger rating (as opposed to having to know what crime they committed) and since they are prisoners they would have to be secured at all times thus allowing for bdsm options such as leashes, cages so forth and as they would be there for potentially a long time you could track there progress as you turn them into whatever you want ( partner, pet, slave) or declare them rehabilitated and release them.
