Within what’s known as the secure transport industry, it’s called “gooning.” Brawny men show up under the cover of darkness and force a teenager into a vehicle, taking them against their will to a boarding school, foster home or treatment center. The process is typically initiated by parents at wit’s end over what to do with a child they perceive as troubled. For the kids, it’s the traumatic first leg of a journey to an unheard-of place, perhaps hundreds of miles away from home.
