FERGUSON, Mo. (AP) — The Federal Aviation Administration is restricting flights over a St. Louis suburb that has seen racial unrest since a white police officer shot and killed an unarmed black teenager. The FAA imposed the restrictions over Ferguson, at the request of St. Louis County police. The move essentially gives police helicopters unfettered access to that air space above the suburb that was subject to riots and looting on Sunday night. That was a day after 18-year-old Michael Brown was shot and killed by an officer.
