December 22-28: Matthew Pixler, Lawrence Chaisson
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 is short with two officers, both with criminal charges. A reminder: these actions of “Being subject of a criminal charge (allegation, not conviction)” are not for any criminal charge against this officer, this only shows on the database for officers with a decertifiable charge — this includes all felonies, and all misdemeanors here. Beyond that, an officer could have charges for anything and the only way to find out would be to know to look.
