Dcity 3rd Edition Suggestion !! Criminal use

I have a suggestion on how to make the Criminal card useful.
at the moment I think we all use this card to control the population or to sell it :) .

So I thought it would be interesting to have a prime jail Card that would convert the negative effects of the Criminal, rewarding either by producing the sim of the jail based on the number of added Criminals and that a negative effect let's say criminals be trained into Worker or another type of Citizen Card

Sorry for the english but I used google translate.
