Two state agencies have cleared Florida Highway Patrol Trooper Daniel Cole of wrongdoing last September when he tasered a young suspect in a hit-and-run accident as she frantically tried to escape. The burly Cole was within reach of Danielle Maudsley, 20, who was handcuffed and had drugs in her system. She fell and hit her head hard on the pavement; she has been in a coma ever since, and doctors say it is unlikely she will wake up. Cole says he would not have done anything differently. Is it time for better taser regulations?
