Denver police and protesters portray different realities in federal trial

Driving the news: On Monday, former Denver police officer Keith Valentine and current Lt. Michael O'Donnell took the stand.

• Their eye-witness accounts clashed with those from the plaintiffs who preceded.

What protesters are saying: Police officers' actions "blew my mind" and reflected a "use of force I've never dreamed I would experience," said Sara Fitouri, a union organizer and resident of Denver, who is one of the 12 injured protesters suing the city.

• She recalled a nearby protester who was trapped in an alley, teargassed and screaming, "We're going to die — they're going to kill us!"

What police are saying: "I saw nothing that alarmed me or concerned me or that I felt was outside" the Denver Police Department's use-of-force policies, said Valentine, who now works for a manufacturer of body cameras for police.

• We were "taking rocks and bottles and canned goods … from all angles," he added.

The big picture: This split-screen view is defining the first-of-its-kind trial, now entering its second week.

What to watch: The days to come will include more testimony from plaintiffs, police commanders and third-party experts. The trial is expected to last three weeks.
