They can charge them as they like, but I'm not seeing how a 14er of any nationality will actually serve time in an adult prison in AZ. If it's in a County jail they will be segregated.
They may charge them like an adult, but they won't be imprisoned like an adult; as in with adults.
And the County will try to send them to State facilities, and the State facilities will try not to take them. Eventually the prison-for-profit bunch will end up with them.
Who pays? You know who.
i was told recently by someone working within the system that it costs the state over 90k a year for every youth incarcerated. Much higher than an adult. the reason for this being rehabilitation, job training, and so on.
