ST. LOUIS (AP) — In the aftermath of Michael Brown's death, legal activists suggested that some of the raw anger that erupted in suburban St. Louis had its roots in an unlikely place — traffic court. It was there, they said, that low-income drivers sometimes saw their lives upended by minor infractions that led to larger problems. A $75 ticket for driving with expired tags, if left unpaid, could eventually bring an arrest warrant and even jail time.
