Thumb on the Scale

The Colorado Department of Public Health and Environment has suspended all blood-alcohol testing, and officials say they plan to randomly retest 800 samples in DUI cases. All currently untested samples will be sent to an independent lab for testing. The moves come after an internal audit found that employees of the state lab that did blood-alcohol testing were not adequately trained, that the lab did not have sufficient staff, that samples were not securely stored and that the lab's supervisor was biased for the prosecution. The audit was completed in March but not released until June.
