More than 400 suspected drunken drivers were arrested over the New Year’s weekend across the state, and more than 1,600 have been arrested since police began holiday sweeps on Thanksgiving. Still, nine people died on state roads in alcohol-related crashes between November 23 and January 4, according to the Colorado Department of Transportation. That’s down from the same period a year ago, when 12 people were killed in DUI crashes, notes The Denver Post. “As we begin a new year, let’s all make a resolution to never get behind the wheel after drinking alcohol,” says Chief James Wolfinbarger of the Colorado State Patrol in a press release. State legislators are peddling harsher penalties, including mandatory jail sentences, that would affect thousands of drivers each year, writes the Post. The cost of incarcerating drivers, however, could be a tough sell as lawmakers grapple with a tight budget. Meanwhile, Timothy R. Bussey, an attorney who defends DUI suspects, has taken a closer look at the mistakes of a Colorado Springs police crime lab, which led to inflated results in about 82 blood-alcohol-content tests, according to the Gazette. “Certainly it was a great cause for concern when a forensic laboratory is committing repeated errors,” Bussey says.
