Week of Jan. 12, 2026: Ryan Gates, Zacheria Hahn, Howard Prince
Welcome to my weekly sum-up. Every Monday I send out a short summary of the last week’s officers that have landed on Colorado’s Peace Officer Standards and Training public database of law enforcement misconduct and actions. They are not necessarily all actions that have happened in the last week, but those that have been added, and consist of any other context I could find.
This week was mostly terminations and resignations with a few veteran officers of decades included.
