(Portland, OR) -- Portland Police are bringing back foot patrols in busy shopping areas through New Year's Eve. They did this last year, and got a positive response. Police Chief Bob Days says the presence of officers provides a level of certainty and confidence. Officers will work in two four hour shifts between noon and 8 p.m. They'll focus on Pioneer Courthouse Square, Southeast Hawthorne, Mississippi and Sellwood. They won't be looking to make arrests, but will respond to life-threatening emergencies and call patrol officers for criminal activity.
