Since 1996, when the deportation laws were hardened, millions of migrants to the U.S., including many long-term legal permanent residents with -green cards, - have experienced summary arrest, incarceration without bail, transfer to remote detention facilities, and deportation without counsel--a life-time banishment from what is, in many cases, the only country they have ever known.
