If you'll permit me to speculate with you for just a minute, when I think this through, this is what occurs to me. We have a population of individuals whose lack of judgment and behaviour has brought them into conflict with the law. It's landed them in a federal penitentiary. That same behaviour that's linked to the disadvantage they have as a result of being FAS-disordered follows them into the institution, so that same lack of judgment, the same behavioural challenges, follows them into the institutional environment.
Prisons are really based on people being able to obey rules, follow instructions, and if you don't, you again bring negative attention to yourself. These are the individuals who are constantly running afoul of institutional rules and regulations, being charged with both minor and major infractions of institutional rules, perhaps receiving punitive sanctions inside because they've been charged with a major infraction where they've had to appear before an independent chairperson. These are folks who don't fare well in front of parole boards. They tend to spend longer time in higher security levels, and they tend to attract segregation placements, etc., so their correctional outcomes are compromised. That's a burden on the system, as well as being a burden on them. They're also more difficult to manage and more expensive for the system.
