A flaw with testing devices that Minnesota law enforcement agencies started using last fall may cause hundreds of DWI cases to be dropped or thrown out. The Bureau of Criminal Apprehension purchased devices that use either of two methods to measure blood alcohol. The BCA has stopped using one of those methods but says there's no problem with the other one.
DWI deaths, arrests down in Minnesota
The annual late-summer enforcement campaign is yielding fewer drunken-driving arrests this year and the number of fatal crashes involving alcohol is continuing a five-year decline, state officials say. Over the past two weekends, 605 drunken drivers were arrested as part of a statewide DWI enforcement campaign. During a similar summer's-end crackdown last year, there were 1,787 arrests over three weekends culminating on Labor Day.
