Before Jesse Williams played a doctor on Grey’s Anatomy, he worked as a teacher. In America Divided, an upcoming EPIX documentary series airing in September, Williams returns to the classroom to report on growing problems in America’s schools, heading to St. Petersburg, Fla. for an in-depth look at that school system’s student achievement gap and the so-called school-to-prison pipeline. In this exclusive clip from the series, which lays bare inequality in America, Williams talks to a public defender about minors in the criminal justice system who are asked to waive their Miranda Rights.
