(Portland, OR)  --  Portland Police performed fewer traffic stops last year, but disparities based on race still exist.  A new report shows traffic stops were down 44-percent, because of the critical shortage of officers.  Less than three-percent of drivers were searched, which the lowest rate on record.  Black and African American drivers were still more likely to be asked for consent to be searched, and they had a higher rate of consent.  The Police Bureau is in the final phase of changing a directive that requires officers to inform drivers of their rights and to get an audio recording of the consent.
