'Traffic stop anxiety': It's real, and cops are smart to have a little

Interesting story from Colorado, written after a shooting at a drunk-driving checkpoint.

A criminal justice professor quoted in the story summed it up this way:

"Anyone who says a traffic stop is routine is just using language for the sake of using language," Sandoval said. "That suggests they all follow the same script.

"But there's always the anxiety and constant danger. An officer may fall into complacency, and all it takes is one time to be complacent for bad things to happen."
