What connection does the author make in regard to the high school and the county jail in the novel, All My Rage?

The prison and county jail are in Friarsfield, California. The author establishes a link between school and jail, with Noor noting that the lockup “sounds – and smells – like Juniper High’s girls’ locker room,” and later thinking that going back to school “sounds about as appealing as the county jail” (260, 291).
