[@Briza] I never really thought about it to be honest but given how hard people have it in the lower areas in terms of the sheer number of people they’d likely get thrown away and forgotten about, no matter the crime. The prison is that big that the chances of finding anyone in there is slim to none. Think of the cells being like those found in some poorer countries, fifty people in a cell meant for ten. So realistically I don’t think parole is an option. As for the judicial system, that’s pretty much left to the police to be judge and jury, in the slums at least.

The only place that gets any sort of semblance of present day justice is the upper and middle tiers. Even then the only crimes that would result in any chance of some sort of parole would be minor crimes. In those circumstances you’d need a lot of cash to pay off certain people. 

Think of it like a worse version of today. Rich can get away with a lot more than poor.
