I'm in agreement that the author's words are a bit dramatic, but I can sympathize with his disposition. Police often use their power as leverage to put citizens in a stressful, fearful state (as to draw out a confession). It's part of their training. Some use it judiciously; others, unnecessarily.

In other words -- Better watch out, Colorado! The cops are out tonight, and they're giving you the shakedown to make sure your ride to the airport is 100% legal.

>>> The officer was just doing his job

Seems to me he was just trying to play detective.
