Heading home from a Chicago gym one morning, 23-year-old Jesus Gutiérrez spotted a grey Cadillac SUV that didn't have any number plates. He didn't think much of it and carried on walking until the vehicle suddenly cut him off.
Two men climbed out, identifying themselves as federal immigration agents and ordering him not to move. They immediately began an intense interrogation, grilling Gutiérrez on his whereabouts, where he had been, and if he had his ID on him.
