Yeah, different people develop differently.

Andrew Medina who is in the program was 15 when he attempted a carjacking (the other two invovled made a deal and got much less time), he is described as being immature.  For the past four years he has been in lockdown in a supermax prison.  He isn't allowed any physical contact with his mother.

His case and the others aren't as clearcut as you describe.

The program will be online sometime Wednesday
