Organized by student groups at Penn, Temple and Drexel, this event brings together entertainers, thought leaders, criminal justice experts, youth organizers and educators — including Rev. Al Sharpton, activist Bryan Stevenson and Meek Mill's mother, Kathy Williams — for a discussion around the U.S. criminal justice system. Titled REFORM: Bringing Injustice to Light, a series of panels will examine Meek's legal case and "inspire attendees to positively push for nationwide reform."
