Spirits were high during a police training exercise Wednesday in Coeur d'Alene. Really high. A handful of volunteers spent the afternoon drinking alcoholic beverages under the watchful eyes of law enforcement officers. The goal was to get the drinkers to various levels of intoxication so they could serve as guinea pigs in an effort to help new officers from throughout the region recognize impaired drivers. Coeur d'Alene Police Officer Nick Knoll, a certified drug-recognition expert, helped organize the so-called wet lab exercise held in a training room at Coeur d'Alene Fire Station No. 2 at the intersection of Ramsey Road and Kathleen Avenue. "It really takes skill to distinguish different levels of impairment," Knoll said/Maureen Dolan, Coeur d'Alene Press. More here.
