Between 2019 and 2023, the Boulder Police Department faced multiple disciplinary actions involving officer misconduct. In 2023 alone, the department received 37 complaints involving 136 allegations of misconduct, with 20 sustained. Violations included failure to investigate cases, sexual harassment, and excessive use of force. Typical punishments ranged from letters of reprimand and additional training to suspensions without pay and resignations. Notably, the department settled a $1 million lawsuit in 2024 over mishandling a sexual assault investigation. These incidents have prompted policy changes, including improved case management systems and enhanced training protocols.
