There are more than 400 high schools in Arizona. You see their students in your neighborhood, walking to school or waiting for the bus, in a nearby Target store shopping for school supplies in late summer, or loudly filling a high school football stadium under Friday night lights.
But there is one Arizona high school whose students you never see. They don’t take the bus. They don’t shop. They don’t go to the game. They don’t even go home after school because home and school are behind the same tall fence topped with razor wire.
