An errant anal probe or catheter once in a blue moon is a small price to pay for a decent, sober society. LEOs are trained, experienced professionals and I’d trust most of them to smell a doper a mile away.

From the article:
Clark was taken to St. Margaret Mercy Hospital where he voluntarily provided a blood sample that produced a 0.07 blood alcohol content reading, just under the 0.08 legal limit.

Officer Djukic was unsatisfied with this result and demanded Clark provide a "voluntary" urine sample.

What part of trained, experienced professionals did I miss ?

...or did I miss your sarcasm tag?

Since there is no quantitative urine test for alcohol, this seems to indicate that, at that point, the police were switching their attention from getting the motorist on DWI to getting him on illegal drug usage or driving under the influence of an illegal drug.
