Rhode Island Attorney General Peter Kilmartin is calling for stiffer penalties for people convicted of driving under the influence causing death.  Legislation filed on Kilmartin's behalf would create some of the toughest crimes in the country for deaths caused by impaired drivers.  Kilmartin says strict penalties, enforcement and education have led to a decline in these crimes, but more needs to be done.  His bill would double the maximum penalty for DUI resulting in death to 30 years in prison.
