POST FALLS – Calls for police service have grown by more than 50 percent over the past five years, but budget constraints have left the Post Falls Police Department unable to hire enough officers to keep pace with the city's population growth. The low-staffing situation became harshly apparent during a Jan. 18 officer-involved shooting outside Real Life Ministries church. That incident, in which a man had earlier fired shots outside the Spokane Valley Hooters restaurant, did not end with any serious injuries but it tied up all of the Post Falls officers who were on duty at the time, said police Lt. Greg McLean.
