He chose to drink. Then he chose to drive. Then he chose to pull the wounded man off his car after he hit him and then he chose to drive away. The driver is not the victim. You can not just let him go because when he is sober he is a different guy. He did not become a drunk overnight. He has had many close calls before. He then chose to wait for his BAC to clear up before he turned himself in. I know how I would react if I hit some one. Not in this fashion with no regard for human life. You can feel sorry for the driver if you want.
