December 1-7: Keith Sandford, Jacob Golden, Jared Palma
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 on the other I could find.
This past week saw a batch of decertifications after the POST Board's quarterly meeting, and a handful of resignations and criminal charges.
A few of these decertifications exemplify how the details the POST database does and does not include can obfuscate an officer’s actions, such as an officer being decertified for lying in an internal affairs report, but not stating the investigation was into their alleged sexual contact with an inmate.

- Employed by Aurora Police Department since January this year
