Department Response

The Pasco Police Department has worked with its partners and initiated efforts to better serve our residents. The following are some examples of those efforts:

  • The Department has obtained State Accreditation.
  • Exploring best-practices from police chiefs around the country by having the Police Executive Research Forum (PERF) conduct a review of policies and training of the Department (PDF).
  • The Department has worked with the Pasco Fire Department and local mental health professionals to implement a "Hotspotters" program to bring mental health services to residents in immediate need.
  • The Department is working to deploy body cameras to all patrol officers.
  • The City and Department have been meeting with the ACLU of Washington and local concerned residents on issues around police training and the use of force and recently completed their collaboration on the Department's updated use of force policy.
  • Participating in the Latino Civic Alliance's Community Visioning Project to better connect law enforcement and the community.
  • Improving communication of the process for police complaints.
  • Expanding Crisis Intervention Training (CIT) to more officers. More than 80% of officers have received CIT training.
  • In response to a request for assistance from United States Attorney Michael C. Ormsby and Pasco Police Chief Robert Metzger, the U.S. Department of Justice's Office of Community Oriented Policing Services (COPS) announced in May 2015 it was offering technical assistance and training to the Pasco Police Department. COPS concluded its assistance in September 2017 (PDF) and noted, "Since May 2015, the PPD has been making great strides to improve the relationship with the community and the communication throughout the agency. The PPD is actively engaging with the community through social media in an impressive manner and becoming a standout agency for its presence…All of these efforts were coordinated, prepared, and executed through the dedication, commitment, and assistance from the personnel at the PPD. The COPS Office has been honored to provide technical assistance support to the PPD, and we commend you on your efforts."
  • Participation in the DOJ's Community Relations Service process.
  • Coordinated regular meetings with local clergy, specifically Latino churches, to improve relations and understanding.
  • The Department was the first agency in the area to implement a citizen academy, and, in 2016, launched a Spanish language-only academy.
  • Implementing social media (Facebook and Twitter) sites that help improve communication with the community, and launching Spanish language versions.
  • Expanding recruitment efforts, focusing on individuals who appreciate serving and reflect diverse communities. The Department encourages bi-lingual applicants and has created a bi-lingual civil service recruitment list. The Department continues to offer pay bonuses for officers proficient in Spanish. These efforts have increased the bi-lingual staff by 50%.
  • In conjunction with the COPS office to help open lines of communications and problem-solving with community members, the Department has started "Coffee with a Cop". "Coffee with a Cop" brings police officers and the community members they serve together in a neutral & casual setting to discuss issues and learn more about each other.
  • Cooperated with the Washington State Commission on Hispanic Affairs that held listening sessions in spring 2015 at Columbia Basin College for members of the public to speak to local, state, and federal officials about the shooting. The Commission, along with members of the City Council and the Department of Justice Community Relation Service (CRS), also held a Hispanic Community Forum in April 2015, hosted by St. Patrick's Parish in Pasco.

This unfortunate incident has caused concern within our community, and the City of Pasco and Pasco Police Department appreciate the continuing efforts of the Department of Justice, local community leaders, and residents to achieve a better understanding of the challenges we face together.
